General Description

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™ technology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series features GTO output control and undershoot corrector in addition to a split ground bus for superior performance.

Features

■ Guaranteed simultaneous switching noise level and

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
