OCTAL BUFFER/LINE DRIVER  
WITH 3-STATE OUTPUTS  
The SN54/74LS540 and SN54/74LS541 are octal buffers and line drivers  
with the same functions as the LS240 and LS241, but with pinouts on the  
opposite side of the package.  
These device types are designed to be used as memory address drivers,  
clock drivers and bus-oriented transmitters/receivers. These devices are  
especially useful as output ports for the microprocessors, allowing ease of  
layout and greater PC board density.
