74ACTQ843

Quiet Series 9-Bit Transparent Latch

with 3-STATE Outputs

General Description

Features

■ Guaranteed simultaneous switching noise level and

The ACTQ843 bus interface latch is designed to eliminate

the extra packages required to buffer existing latches and

provide extra data width for wider address/data paths. The

ACTQ843 utilizes Fairchild FACT Quiet Series technol-

ogy to guarantee quiet output switching and improved

dynamic threshold performance. FACT Quiet Series fea-

tures GTO output control and undershoot corrector in

addition to a split ground bus for superior performance.

dynamic threshold performance

■ Guaranteed pin-to-pin skew AC performance

■ Inputs and outputs on opposite sides of package for

easy interface with microprocessors

■ Improved latch-up immunity

■ Outputs source/sink 24 mA

■ ACTQ843 has TTL-compatible inputs

■ Functionally and pin-compatible to AMD’s AM29843

■ 3-STATE outputs for bus interfacing
