54ACTQ14 Quiet Series Hex Inverter with Schmitt Trigger Input General Description termined internally by transistor ratios and is essentially insensitive to temperature and supply voltage variations. 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 de- n ICC reduced by 50% n Guaranteed simultaneous switching noise level and dynamic threshold performance n Improved latch-up immunity n 4 kV minimum ESD performance n Outputs source/sink 24 mA n Standard Microcircuit Drawing (SMD) 5962-92183 Logic Symbol Connection Diagrams IEEE/IEC Features Pin Assignment for DIP and Flatpak DS010911-4 DS010911-3 Pin Assignment for LCC Function Table Input Output A O L H H L Pin Names Description In Inputs On Outputs DS010911-5 GTO™ is a trademark of National Semiconductor Corporation.
