74ACTQ14 Quiet Series Hex Inverter with Schmitt Trigger Input

74ACTQ14
Quiet Series Hex Inverter with Schmitt Trigger Input

General Description

The ACTQ14 contains six inverter gates each with a
Schmitt trigger input. They are capable of transforming
slowly changing input sign als into sharply defined, jitter­free output signals. In ad dition, they have a great er noise
margin than conventional inverters.

The ACTQ14 utilizes Fairchild Quiet Series Technology
to guarantee quiet output switchin g and improve dy namic
threshold performance. FACT Quiet Series features
GTO output control and unde rshoot corre ctor in add ition
to a split ground bus for superior performance.

The ACTQ14 has hysteresis between the positive-going
and negative-going i nput threshold s (typically 1.0 V) which
is determined internally by transistor ratios and is essen­tially insensitive to temp erature and supply voltage varia­tions.

Features

■ ICC reduced by 50%

■ Guaranteed simultaneous switching noise level and

dynamic threshold performan ce

■ Improved latch-up immunity

■ Guarante ed pin-to-pin skew AC performance

■ Outputs source/sink 24 mA

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 outside of databook s pecifications.
