54ACTQ841

Quiet Series 10-Bit Transparent Latch with TRI-STATE^®

Outputs

General Description

Features

n Guaranteed simultaneous switching noise level and

dynamic threshold performance

The ’ACTQ841 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 or

buses carrying parity. The ’841 is a 10-bit transparent latch,

a 10-bit version of the ’373. The ’ACTQ841 utilizes NSC

Quiet Series technology to guarantee quiet output switching

and improved dynamic threshold performance, FACT Quiet

n Inputs and outputs on opposite sides of package allow

easy interface with microprocessors

n Improved latch-up immunity

n Outputs source/sink 24 mA

n ’ACTQ841 has TTL-compatible inputs

n Standard Microcircuit Drawing (SMD) 5962-92200

™

Series features GTO output control and undershoot cor-

rector in addition to a split ground bus for superior perfor-

mance.
