Inverter Gates FAQ

How does the Schmitt trigger function benefit signal processing?

It converts slowly changing input signals into sharply defined, jitter-free output signals by utilizing different switching thresholds for positive and negative-going transitions.

Can the inputs interface with voltages higher than VDD?

Yes, the integrated clamp diodes allow the use of current-limiting resistors to safely interface inputs to voltages exceeding the supply voltage.
