Hello Rich,


And an "R" or an "S" input doesn't need a lot of noise immunity -
once it's reset, it's reset! ;-)


Ahem, if it's not a Schmitt input then rather bizarre things can happen
when applying the ramp of a slowly charging cap. Stuff like both Q and
/Q being high at the same time and occasionally that is followed by
something that can't take that and croaks. Like an H-bridge.

Yeah, and the H-bridge was in charge of keeping the sattelite in orbit.

Gravity usually does a pretty good job of keeping satellites in orbit.
Some day we will have to go up there and de-orbit all the crap that has
accumulated over the years.
