74AC14 • 74ACT14
Hex Inverter with Schmitt Trigger Input
General Description
The 74AC14 and 74ACT14 contain six inverter gates each with
a Schmitt trigger input. They are capable of transforming slowly
changing input signals into sharply defined, jitter-free output sig-
nals. In addition, they have a greater noise margin than conven-
tional inverters.
The 74AC14 and 74ACT14 have hysteresis between the posi-
tive-going and negative-going input thresholds (typically 1.0V)
which is determined internally by transistor ratios and is essen-
tially insensitive to temperature and supply voltage variations.
