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 transform-
ing 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 (typi-
cally 1.0V) which is determined internally by transistor
ratios and is essentially insensitive to temperature and sup-
ply voltage variations.
Features
s ICC reduced by 50%
s Outputs source/sink 24 mA
s 74ACT14 has TTL-compatible inputs

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, with-
out exception, to ensure that the system design is reliable over its power
supply, temperature, and output/input loading variables. Fairchild does not
recommend operation of FACTcircuits outside databook specifications.
