74AC14 • 74ACT14 Hex Inverter with Schmitt Trigger Input
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.

Absolute Maximum Ratings(Note 2)
Recommended Operating
Conditions
Note 2: Absolute maximum ratings are those values beyond which damage to the
device may occur. The databook specifications should be met, without exception, to
ensure that the system design is reliable over its power supply, temperature, and out-
put/input loading variables. Fairchild does not recommend operation of FACT cir-
cuits outside databook specifications.
