description  
These octal bus transceivers are designed for  
asynchronous two-way communication between  
data buses. The control-function implementation  
minimizes external timing requirements.

SN54ACT245 . . . FK PACKAGE  
(TOP VIEW)  
When the output-enable (OE) is low, the device  
passes noninverted data from the A bus to the B  
bus or from the B bus to the A bus, depending  
upon the logic level at the direction-control (DIR)  
input. A high on OE disables the device so that the  
buses are effectively isolated.
