54ACTQ541
Quiet Series Octal Buffer/Line Driver with TRI-STATE

®

Outputs

General Description

The ’ACTQ541 is an octal buffer and line driver with
TRI-STATE outputs designed to be employed as a memory
and address driver, clock driver, or bus-oriented transmitter/
receiver.

The ’ACTQ541 is similar to the ’ACTQ244 while providing
flow-through architecture (inputs on opposite sides from out­puts). This pinout arrangement makes this device especially
useful as an output port for microprocessors, allowing ease
of layout and greater PC board density.

The ’ACTQ541 utilizes NSC Quiet Series technology to
guarantee quiet output switching and improved dynamic
threshold performance. FACT Quiet Series
