74F14

Hex Inverter Schmitt Trigger

totem-pole output. The Schmitt trigger uses positive feed

back to effectively speed-up slow input transition, and pro-

vide different input threshold voltages for positive and neg-

ative-going transitions. This hysteresis between the

positive-going and negative-going input thresholds (typi-

cally 800 mV) is determined internally by resistor ratios and

is essentially insensitive to temperature and supply voltage

variations.

General Description

The 74F14 contains six logic inverters which accept stan-

dard TTL input signals and provide standard TTL output

levels. They are capable of transforming slowly changing

input signals into sharply defined, jitter-free output signals.

In addition, they have a greater noise margin than conven-

tional inverters.

Each circuit contains a Schmitt trigger followed by a Dar-

lington level shifter and a phase splitter driving a TTL
