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.
