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.  
Features  
ICC and IOZ reduced by 50%  
3-STATE inverting outputs  
Inputs and outputs opposite side of package, allowing  
easier interface to microprocessors  
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.  
Output source/sink 24 mA
