'2.7Vgs Threshold Logic Level FET's'

Hi,

I need to switch some devices that exceed the port capabilities of a PIC. I
have found some International rectifier 2.7Vgs threshold logic level FET's,
i.e. IRF7307. What are some other favorites of you PIC listers? I would like
to find a nice source for single or dual device, through hole 2.7Vgs
threshold N and P channel FETS.

I am also looking for a nice NEMA4/IP65 bezel for an LCD display. I have an
application that has a small LCD that sits out in the weather. I would like
to buy a weather tight bezel rather than make one.

Thanks,

- -Mark

A very handy logic level FET :   2N7000

Zetex has a selection of these.

    What is your RDS_on, VDS max requirements?
       Look at IR's Z series that contains the letter "L" such as IRFLZ24
    these devices typically have Vgs thresholds in the 1 to 2 Volt range.
    If you need more power, Siemens has some nice "Smart Drives" such as
    the BTS410 series which takes TTL inputs and provides high power
    output (via internal charge pumps) with a diagnostic line to boot
    (Viele Duetsch Marks).  Siliconix is my favorite with SO8 duals,
    singles, and mixed P/N Channels in the same package.  Not much power
    dissipation, but very small.  National, Mot, IR, and Harris are
    creating similar products, but Siliconix seems to be the leader in
    innovation.

    I am also interested in the above, please let us know what you find
    out.
