54AC541
Octal Buffer/Line Driver with TRI-STATE® Outputs
General Description
The ’AC541 is an octal buffer/line driver designed to be em-
ployed as memory and address drivers, clock drivers and
bus oriented transmitter/receivers. The ’AC541 is a nonin-
verting option of the ’AC540.
This device is similar in function to the ’AC244 while provid-
ing flow-through architecture (inputs on opposite side from
outputs). This pinout arrangement makes this device espe-
cially useful as an output port for microprocessors, allowing
ease of layout and greater PC board density.
Features
n ICC and IOZ reduced by 50%
n TRI-STATE outputs
n Inputs and outputs opposite side of package, allowing
easier interface to microprocessors
n Output source/sink 24 mA
n ’AC540 provides inverted outputs
n Standard Military Drawing (SMD)
