OK, I just had the *weirdest* experience of my life.
Spooky.
I am working on wiring up the IPL circuit as documented at
http://www.falvotech.com/projects/kestrel/repo/8k/prints/ipl-port_3.pdf
. I plugged power in, and I ran the software on my Linux box to
program it (wrote it myself; sources coming soon). I probed around
with the o'scope, and everything was working.
Perfectly.
Shortly afterwards, I noticed that Vss of U301 was not hooked up to
anything!! Vdd was connected to +5V, as expected. And yet, it worked
fully.
Anyone else ever have something like this happen? I know this is
pretty much just a fluke, but I'm wondering *why* it worked?
Anyway, I hooked Vss back up, and the circuit operation didn't change
at all. :-)
