555 timer schmitt trigger logic inverter – NOT gate

Table of Contents

Tying pin 2 (trigger) and 6 (threshold) together allows them to monitor the same input voltage. An input above 2/3 supply voltage sets pin 3 (output) and pin 7 (discharge) low. An input below 1/3 supply sets the output high, and disconnects the discharge pin so that it does nothing. The range of voltage between 1/3 and 2/3 is the hysteresis. Hysteresis is voltage range where it leaves the output in whatever state it was last put in to.

Assortment of commonly used integrated circuits (IC). I made a lot of videos with them.

A similar symbol to the threshold I drew below is drawn into the logic gate symbol when it has a schmitt trigger output.
