54ACTQ14
Quiet Series Hex Inverter with Schmitt Trigger Input
General Description
The 鈥橝CTQ14 contains six inverter gates each with a Schmitt
trigger input. They are capable of transforming slowly chang-
ing input signals into sharply defined, jitter-free output sig-
nals. In addition, they have a greater noise margin than con-
ventional inverters.
The 鈥橝CTQ14 utilizes NSC Quiet Series Technology to guar-
antee quiet output switching and improve dynamic threshold
performance. FACT Quiet Series

control and undershoot corrector in addition to a split ground
bus for superior performance.
The 鈥橝CTQ14 has hysteresis between the positive-going and
negative-going input thresholds (typically 1.0V) which is de-
termined internally by transistor ratios and is essentially in-
sensitive to temperature and supply voltage variations.
