54AC541
Octal Buffer/Line Driver with TRI-STATE

®

Outputs

General Description

The ’AC541 is an octal buffer/line driver designed to be em­ployed as memory and address drivers, clock drivers and
bus oriented transmitter/receivers. The ’AC541 is a nonin­verting option of the ’AC540.

This device is similar in function to the ’AC244 while provid­ing flow-through architecture (inputs on opposite side 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.
