74ACTQ14
Quiet Series錚?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錚?Technology
to guarantee quiet output switching and improve dynamic
threshold performance. FACT Quiet Series錚?features
GTO錚?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.
