on, off, and the other thing
- tyingq 1y agohi-z is one choice. Though I don't know how well that does past a certain speed.
- duskwuff 1y agoIt works poorly at any speed. Hi-Z is an undriven signal, not a specific level, so voltage-driven logic like (C)MOS can't distinguish it from an input that's whatever that signal happens to be floating at. In current-driven logic like TTL or ECL, it's completely equivalent to a lack of current.
- tyingq 1y agoI wasn't pitching it as a solid commercial idea. Just that you can get (perhaps fiddly) three states out into the real world with something cheap that already exists.

- ForOldHack 1y agoUsing 8 way quadrature and high-z, you have 16 values packed into 1 quasi-hexalogic gate. May your hydration prove fruitful.
