Overview
The MC74ACT14DTR2G is a Hex Inverter Schmitt Trigger integrated circuit produced by onsemi. This device contains six logic inverters that accept standard CMOS input signals, as well as TTL-compatible inputs for the MC74ACT14 variant. It is designed to transform slowly changing input signals into sharply defined, jitter-free output signals, offering a greater noise margin compared to conventional inverters. The MC74ACT14DTR2G features internal hysteresis between the positive-going and negative-going input thresholds, which is insensitive to temperature and supply voltage variations.
