MC74AC14/D

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.
