Description

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 essentially

insensitive to temperature and supply voltage variations.
