Subject: [alt-beam] Re: Schmitt trigger
Back on topic (using Various Thoughts as the bifurcation point), these 4
pin (SMD) single Schmitt critters are available from Toshiba. I think that
wasting part of a chip sort of violates my design rule of "maximal
utilization of minimal resources" which is the designer's equivalent to
using Occam's Razor. Having said that, single sided (home workshop) PCB
layout is often made a lot easier by adding an extra chip or a transistor
instead of jumper wires you would need to get that extra inverter to one end
of the board from a spare gate in a chip on the other end.
