'Help me - fast..... (reset line)'

Hey everyone.  "I've left my databook at home so I can't order up."

I'm wanting to order some of these nifty little Panasonic voltage detectors
I see in the Digi-Key catalog to see how they work with the PICs.  What I
can't remember though is the polarity of the reset line on the PIC.  I believe
that it is active LOW?  Meaning - when the line is low, the pic is in a reset
state - right?  When it is HIGH, the PIC comes to life - can you clarify this
for me so I can place the order.  If you like, I'll tell you all how they
work.  BTW, they are less expensive than the Econo-resets we've talked about
before.  They are only 80 cents in quantities of one, 72 cents for 10, and
54 cents for quantities of 100 or more.  Oh, and any suggestions on the
detection voltage I should use?  My regulator is 5V so I think I'm going with
the 4.2 to 4.5 volts.  I COULD use the 4.6 to 4.9 but I don't want my PIC
resetting everytime I turn on a fan.....

Anyway, your help will be GREATLY appreciated...!!!

Yes, that seems to be quit right.


Have fun.

Your correct!

They sound like great devices.  I'll be interested to know how they work.
