74AC14/D

Hex Inverter with Schmitt

Trigger Input

74AC14, 74ACT14

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 signals.

In addition, they have a greater noise margin than conventional

inverters.

The 74AC14 and 74ACT14 have hysteresis between

the positive−going and negative−going input thresholds (typically

1.0 V) which is determined internally by transistor ratios and is

essentially insensitive to temperature and supply voltage variations.
