74AC540
Octal Buffer/Line Driver with 3-STATE Outputs
General Description
The AC540 is an octal buffer/line drivers designed to be
employed 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 microproces-
sors, allowing ease of layout and greater PC board density.
Features
s ICC and IOZ reduced by 50%
s 3-STATE inverting outputs
s Inputs and outputs opposite side of package, allowing
easier interface to microprocessors
s Output source/sink 24 mA
