|54ACTQ14 Quiet Series Hex Inverter with Schmitt Trigger Input
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 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.Features

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 to +125�C.
