74ACTQ14
Quiet Series Hex Inverter with Schmitt Trigger Input
General Description
The ACTQ14 contains six inverter gates each with a
Schmitt trigger input. They are capable of transforming
slowly changing input signals into sharply defined, jitter-
free output signals. In addition, they have a greater noise
margin than conventional inverters.
The ACTQ14 utilizes Fairchild Quiet Series Technology
to guarantee quiet output switching and improve dynamic
threshold performance. FACT Quiet Series features
GTO output control and undershoot corrector in addition
to a split ground bus for superior performance.
The ACTQ14 has hysteresis between the positive-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 varia-
tions.
Features
