3 Description

Each circuit in SNx414 and SNx4LS14 functions as

an inverter. However, because of the Schmitt-Trigger

action, they have different input threshold levels for

positive-going (VT+) and negative-going (VT–

) signals.

These circuits are temperature compensated and can

be triggered from the slowest of input ramps and still

give clean, jitter-free output signals.
