74AC14, 74ACT14

Hex Inverter with Schmitt Trigger Input

Features

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 (typi-

cally 1.0V) which is determined internally by transistor

ratios and is essentially insensitive to temperature and

supply voltage variations.

Ordering Information

Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
