74AC14, 74ACT14
Hex Inverter with Schmitt Trigger Input
Features General Description
I reduced by 50% The 74AC14 and 74ACT14 contain six inverter gates
CC
each with a Schmitt trigger input. They are capable of
Outputs source/sink 24mA
transforming slowly changing input signals into sharply
74ACT14 has TTL-compatible inputs
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
supply voltage variations.
