I just looked at a schematic I pulled off the net and I noticed that the
Designer has a pullup resistor (to vcc) and a pulldown resistor (to
ground) on the chip input.
Exactly why is this done this way?
I am used to seeing either one or the other.
pullup for normally high
or
pulldown for normally low
Forgive me, I am a software guy who takes an interest in such things. Thanks
