How to 'de-mux' a tri-state pin?
I would like to use a single pin (tri-state buffer, 3.3V logic in case this matters) to drive two P-channel MOSFETs as high-side switches. Only one of them will be 'on' at any time. When the pin is in ...

"Working" tri-state MOSFET Push-Pull leakage
I have been working for a while on this design, where there are 9 push-pulls that should drive a charliplexed LED array. Therefore the circuit must be able to provide three states, namely: HIGH(12V), ...

Tri-state push-pull configuration GPIO protection
I am designing a sort of "driver" for a high voltage Charlieplexed LED array, since normal GPIOS can't handle 12V. For that, I need to be able to use tri-state logic, which means LOW, HIGH, ...
