HD74AC14
Hex Inverter Schmitt Trigger
Description
The HD74AC14 contains six logic inverters which accept standard CMOS input signals (TTL levels for
HD74ACT14) and provide standard CMOS 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 conventional inverters.
The HD74AC14 has 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.
