54ACTQ14
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 NSC QuietSeries 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 hysteresisbetweenthepositive-goingand
negative-going input thresholds (typically 1.0V) which is de-

termined internally by transistor ratios and is essentially in­sensitive to temperature and supply voltage variations.

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, without
exception, to ensure that the system design is reliable over its power supply,
temperature, and output/input loading variables. National does not recom­mend operation outside of databook specifications.

Note 2: All commercial packaging is not recommended for applications re­quiring greater than 2000 temperature cycles from −40˚C to +125˚C.
