74AC14, 74ACT14 — Hex Inverter with Schmitt Trigger Input
February 2011
74AC14, 74ACT14 Hex Inverter with Schmitt Trigger Input
Features
■ ICC reduced by 50% ■ Outputs source/sink 24mA ■ 74ACT14 has TTL-compatible inputs
General Description
The 74AC14 and 74ACT14 contain 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 74AC14 and 74ACT14 have hysteresis between the positive-going and negative-going input thresholds (typically 1.
0V) which is determined internally by
transistor ratios and is esse...
