Hello,

Feeding my source through an inverting gate and a non-inverting gate is
exactly what I hope to do.  What I am wondering is if you can buy an IC that
contains both an inverting gate and a non-inverting gate or if I need to use
to different IC's and try and match their delays (or build an adjustable
delay circuit).  Brent Brown (thanks!) pointed me to the TC4428A - do you
know another IC?

tolerate. If you use a fast logic device, you can probably achieve your
goal. I believe 74Sxx or 74Hxx device should suffice. If you need closer to
zero delay, feed your source through an inverting gate and a non-inverting
gate which should give you satisfactory results.

small time delay leaving the two signals to not be exactly 180 degree out of
phase.  I imagine this is a common problem and suspect an inverter with
matched buffer IC exists that allows you to reduce this error.  Does such an
IC exist? Can anyone give me a part number? (I was suprised to find my
search of Digikey turn up nothing, but I'm not sure exactly what to search
for)
