54AC540
Octal Buffer/Line Driver with TRI-STATE^® Outputs
General Description
The ’AC540 is an octal buffer/line drivers designed to be em-
ployed as memory and address drivers, clock drivers and
bus oriented transmitter/receivers.
These devices are similar in function to the ’AC240 while
providing flow-through architecture (inputs on opposite side
from outputs). This pinout arrangement makes these devices
especially useful as output ports for microprocessors, allow-
ing ease of layout and greater PC board density.
Features
n I_CC and I_OZ reduced by 50%
n TRI-STATE inverting outputs
n Inputs and outputs opposite side of package, allowing
easier interface to microprocessors
n Output source/sink 24 mA
