I sampled four different IC-types from National this weekend, all were
some kind of motor interface-ICs. Today I got four mails (one per
sampled IC-type) from National, all saying that they're sorry and they
have to charge me a small shipping fee since I'm outside the US.
No problems with that, I thought, so I opened the four links where I
could add my Visa-card etc. These "small" fees were, in order: $80.40,
$73.40, $77.40, $66.20, making a total sum of $297.40 - which
DEFINATELY is a "small fee", yessir!
Too bad, because I was a potential customer.
So I googled around for other manufacturers.I found Intersil, but
their web pages were even more braindead; when I "sampled" the parts,
what the web did was to add my email address to a mailing list for the
particular part type.
Are there any other MOSFET H-bridge IC-manufacturers with the ability to sample?

Maybe they are having Bob Pease hand deliver the samples these days. :)
This is so bizarre that you have just done this as this is EXACTLY what I
have done today but in reverse :-o
I need some H-Bridge drivers and chips and some switchers as samples and put
my sample order in with Intersil first.
If you go back onto the Intersil site and click on samples now it will let
you add them - you might need to copy and paste the part numbers after the
initial sample order. Thats what I ended up doing.
I then placed orders from the Natsemi site but haven't had anything back yet
(finished 5 minutes ago).
Will be interesting to see if I get some massive shipping/handling charge
requests from Natsemi now.

Hehe, National used to be forefront on the "parts I go to by default"
list because they had a great assortment of parts, and a REALLY good
sample system.
They then started limited their samples to people with "certain" email
addresses (basically they removed people with "generic" email addresses
like yahoo.com). That was fine for me, since I used a non generic
address.
They the limited addresses more, but gave no explanation as to which
were OK and which weren't. I was in school at the time, using my school
address, which they said should be fine, but wasn't. Tried using every
email address I had, none were "approved". So I dropped them. Haven't
been to their site since.
It's a shame, their parts were pretty good, but their competitors have
"reasonable" sample programs, so why should I go with National? If they
make it that hard and expensive to get a few samples, how are they going
to be when you need a little support? I don't care to find out.

Thanks for letting me know. This info was correct, when returning to
the sample-page I was finally able to fill the part-numbers.
Now I'm just hoping they're sending them as well, without these
ridicule "small shipping fees" as National's.
Have you contacted your local reps? Being in the USA, never been charged shipping for samples, especially when they come thru the reps. But, are you *sure* all your getting is chips, or maybe demo boards? I know National has a program where you can get a demo board designed quick, and depending on the situation, can get them free..but will sometimes charge for them.
I'd be whining to the rep for those kinds of charges.

I also had great experience with Allegro. They have good selection of H-bridges
and a good sample program. I think you can get 3-4 parts for each part number,
quite enough to try.

I was allowed to select up to 6 of the current sensor I wanted, though the
quantity may vary according to cost of chip, but this was my only
experience.
Well I've just had confirmation back on my order from National Semiconductor
for the samples I placed an order for yesterday.
Its a total of $270.60 for the shipping and handling charge.
It would be cheaper to fly over to the states on a budget airline and get
them in person.
I will try the local distributors in the UK to see if they will provide me
with any but at the moment it looks like Intersil will be getting my future
business for the equivalent parts.
yes...well, for me the reps and distie's are not obsolete. I use/abuse them on a daily basis, Maybe in other parts of the world they are not effective tools, but when you need to get inside a mfg...ie...TI...and get information not usually available, or be able to talk to the lead designer on a product...its the rep's that get me in that door.

Lots of people at my school sample from Microchip constantly. I know a
guy who puts in the maximum numbers of samples allowed as frequently as
he can, about 4 types of chips, 3 each, once a month.
Microchip never complains and this is comming from an arts school!
I know a guy who even got them to send about 50 free 12x series chips to
him for an arts project, he listed microchip as one of his sponsers.
I believe, they let you sample some parts absolutely free (no s/h
charges). Others are available at a 'small' fee which they clearly
mention while you are placing the order. IIRC, the reason they give is
that there is a huge demand or something like that for that part.

No.
The first time I tried to sample from National (it was a LED-bar
driver IC, don't remember the actual part number), the web page said -
BEFORE i clicked "confirm" - that this particular IC has a huge demand
and they have to charge shipping fee etc, and that time it would cost
me $13 to get them sent. The second, which initiated this thread, did
not have this "huge demand"-warning, but the fee was more than six
times higher.
I do however not only want to rant at National, because they are the
only company that sent me a _printed_ databook for free. For any other
manufacturer, the answer was something like "we don't have databooks
anymore, use the pdf-files". For me, who does not like reading big
reference manuals in front of a computer screen, this pdf-only thingy
is a backstab.

However to be fair, the cost of producing those books must be horrendous,
and realistically only a very small proportion (if any) of each one gets
read. Not only that but the saving in tree cutting for paper must be
significant as well, across all semiconductor manufacturers.
At least with a PDF you know (?) you are getting the most recent version
from their website, you can get the sheets for the newest chips often before
they appear in the local press (when you live in the far reaches like NZ or
UK), and you can also download errata sheets for a lot of chips. App notes
are also readily available.
It is easy enough to print a datasheet, and Acrobat will allow you to put
multiple pages on one side, so doing 2 A5 pages to one side of a sheet of A4
paper, double sided allows 4 pages to a sheet (but not necessarily in an
order that allows you to staple it like a paper datasheet), means using
considerably less paper if you really must have a printed copy, and yes I
like to sometimes as well.
Also having datasheets available on web sites makes a chip manufacturer more
accessible to everyone. If I had to go get a databook from a rep in many
cases I wouldn't know who to look for - certainly before the web came along.
And I have a story against National as well - for many years they had an
agency in New Zealand who had served them well, selling considerable
quantities for the size of the country. Then about late 1970s National
decided off their own bat to terminate this distributor, and make (IIRC)
Dick Smith (a Radio Shack style operation) their distributor. Instantly the
range of chips available became very limited, and what DS did know about was
generally not in stock. The sales to NZ must have had a steeper fall than
stock prices in a wall street crash.

I am not so sure. I have a 1 meter pile of printed pdfs somewhere, but
when I need let's say the 7805 specs I simply print it again, browsing
through the pile would take too much time (most of that was printed with
printers that could neither do 2-on-1, nor double-sided). Those old
databooks were mostly printed on very thin paper, I wish I could order
such a thin-paper book of a specified set of pdf datasheets!

Agreed. In the days when chips were more "static" in functionality (i.e.
TTL logic chips) databooks kinda made sense (you used the book for
functionality and pinout info, and online info for up to date timing
specs).
These days though, chips are in such flux you'd NEVER have an up to date
book (so you'd still end up online with the pdf), and even if you had a
book, you'd need a new edition every few months just to keep up. Perfect
proof of this is digikey's catalogs, every one I get is thicker then the
one before it.
I once had a collection of databooks from NS. I barely ever used them
(finally threw them out when I moved). It was just faster and easier to
go online and get the info (which was usually more up to date then the
books), and this was in the days of 9600 baud modems (yes, it sometimes
took an hour to download a datasheet)!
I however do agree that fully reading a datasheet is much better on
paper, so when I do need to look at a whole datasheet (i.e. for the
enc28j60) my solution is printing 4 pages per sheet and using a spiral
binding.

But do you REALLY print out the whole datasheet? Generally I print out
only two or three pages of a datasheet for a part I'm using: the pinout,
the "pin functions" and an example app. For more nitty gritty I just
open my laptop.

depends: when I know what I want I of course print out just that (Can't
even remeber how often I printed the pages with pinouts of various
PICs), but when I am not familiar with the chip and the interface is
complicated I must print out most of the datasheet. I hate it when I am
reading (in bed, in the garden, wating for a train, etc) and some
essential part is missing. Of course i walways try to avoid the humbug
pages at the end, especially the ones with PCB layouts. Unfortunately
some manufactureres like big dark logo's on every page :(

I use FinePrint for such things. It can print in booklet form, so that you
can at the end fold the whole staple in the middle, staple or otherwise
bind it, and have all the pages in the correct order.
Nowadays some printer drivers can do that, but not all, and I started using
it when pretty much no printer driver could do that.

Ofcourse, I'm fully aware that keeping those databooks up to date was
not a cheap job in the early days, and definately not cheap today
either since the world is constantly evolving.
What I want databooks for is to get a general overview for products. I
like browsing page by page in case I happen to find a nice chip or
something like that. If it looks useful, I might sample it, build some
circuits around it, and then continue doing so.
For a situation like that, the pdf would certainly be the way to go to
keep me updated with the chip-in-question's datas, but the book would
get me into the "mode of knowing" about the chip. I'm still a hobbyist
and I've yet got a long learning path to go, so I don't know even a
tenth of a percent of all tips, tricks, ICs etc out there. For me,
it's an eternal - but outrageously interesting! - jungle.
For me, a databook would be my kind of machete to pacefully step
forward along the path. Trying to walk the path using pdf:s would kind
of be like tampering with quicksand. Stepping and struggling but
without any grip.

Yeah. While I never minded lying to companies to get free samples
from companies when I was a student, I always felt a bit guilty when
they ended up paying many times the cost of the chip to ship me a
massive databook with it. (Not that companies seem to be very
efficient about shipping chips weighing less than an ounce by
first class mail, anyway. Sigh.)

Yes, I did/do enjoy browsing through a good databook.

I ordered a load of stuff from Mouser while I was staying in New York. It all arrived, but a pack of 10 diodes only had three in it, so I contacted them.
Unfortunately I was about to fly home, and told them this - they said they'd send the missing parts to the UK. When they arrived, by Global Priority,
they were in a 6" cubic cardboard box, with conductive bubble-wrap filling it, then a conductive plastic bag containing the mylar packet with the 7
tiny diodes in it, and six copies of the shipping document! They could have just popped them in an ordinary envelope, or perhaps a bubble-padded
envelope, and saved themselves and the planet a ludicrous amount of cost/waste. Surely someone must have thought as they were packing it that it
was ridiculous? Don't firms have a way for employees to report stupid situations so they can be improved?

I'd apprecaite what they have done. ;-)
By the way, I think a lot of US companies do follow "SOP" or Standard
Operatiion Procedure. So Mouser is one of them.
We've actually had this discussion here a few years ago, where I was
questioning why Analog Devices sent me 2 very small chips (8-TSOP IIRC) in a
huge box, etc. One very plausible answer was that they only have
certain-sized packages which simplifies and speeds up their packaging
process. As I am now in production with my products, I agree that keeping
only a few different sizes of boxes on hand is more cost effective and faster
to deal with than many different sizes.
Also, although my most popular box size is 6" x 4" x 4", I have to sometimes
package it in a bigger box for international shipping as the post-office
complains that the label/customs forms won't fit on it.
Cheers,
-Neil.

I got mine from Intersil at the end of last week - rapid delivery. I also
received some samples from ST yesterday (also very good service).
I sent them both a quick "thank you" through their online "contact us" form
for the excellent service received and received a personal reply from both
of them by email the same day.

Sometimes it doesn't matter. The "process" is ISO 900X "certified" and
can't be changed without great expense.
ISO 900x certification is not a guarantee of quality, just a way to
prove you do it the same every time, whether that way makes any sense or
not.
The Firestone tire plant that produced tires that killed hundreds of
people, was ISO 9001 certified. It's one of my co-worker's favorite
photos, a shot of the plant, closed down, and the caption talking about
how the plant's production system was grossly negligent and deficient.
It keeps those who think we should have ISO 900x certifications here, at
bay.
And the truth of the matter is, no. Most companies don't have
suggestion boxes or any other way of making recommendations anonymously.
