How does an Inverted Schmitt Trigger work?
It is basically a normal inverter with Schmitt Trigger input levels, thus a Low input results in a High output vice versa. Due to some positive feedback, switching from Low to High has a higher switching threshold than switching from High to Low. This prevents illegal switching if the signal is noisy or if the transitions are slow. Example integrated circuits: 74xx14, where xx=LS,HC,…
