74AC14 • 74ACT14 Hex Inverter with Schmitt Trigger Input

74AC14 • 74ACT14
Hex Inverter with Schmitt Trigger Input

General Description

The 74AC14 and 74ACT14 co ntain six invert er gates ea ch
with a Schmitt trigger input. They are capable of transform­ing slowly changing input signals into sharply defined, jitter­free output signals. In ad dition, they have a great er 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 essentially insensitive to temperature and sup­ply voltage variations.

Features

■ ICC reduced by 50%

■ Outputs source/sink 24 mA

■ 74ACT14 has TTL-compatible inputs

Absolute Maximum Ratings(Note 1) Recommended Operating

Conditions

Note 1: Absolute maximum ratings are those values beyond which damage

to the device may occur. The databook specifications should be met, with­out exception, to ensure that the system design is reliable over its power
supply, temperature, and ou tput/inp ut loadi ng varia bles. Fairchild does no t
recommend operat ion of FACT circuits outside da t abook specifications.
