74AC14, 74ACT14 Hex Inverter with Schmitt Trigger Input February 2011 74AC14, 74ACT14 Hex Inverter with Schmitt Trigger Input Features General Description I reduced by 50% The 74AC14 and 74ACT14 contain six inverter gates CC each with a Schmitt trigger input. They are capable of Outputs source/sink 24mA transforming slowly changing input signals into sharply 74ACT14 has TTL-compatible inputs defined, jitter-free output signals. In addition, they have a greater noise margin than conventional inverters. The 74AC14 and 74ACT14 have hysteresis between the positive-going and negative-going input thresholds (typi- cally 1.0V) which is determined internally by transistor ratios and is essentially insensitive to temperature and supply voltage variations.
