The MC74AC14/74ACT14 is a device that contains six logic inverters which accept standard CMOS input signals (TTL levels for MC74ACT14) and provide standard CMOS output levels. 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 MC74AC14/74ACT14 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.
This document provides technical specifications for the Motorola MC74AC14 and MC74ACT14 integrated circuits. These devices contain six logic inverters with built-in hysteresis (Schmitt Trigger) that accept standard CMOS or TTL-compatible input signals to provide sharply defined, jitter-free output signals.
The datasheet details maximum ratings, recommended operating conditions, DC and AC electrical characteristics for both the 74AC and 74ACT series variants. It also includes outline dimensions for the available N (DIP) and D (SOIC) plastic packages.
