MC74AC14
MC74ACT14
Hex Inverter Schmitt Trigger
The MC74AC14/74ACT14 contains six logic inverters which accept standard
CMOS Input signals (TTL levels for MC74ACT14) 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 then conventional inverters.
The MC74AC14/74ACT14 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.
