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

SN54HC245 . . . FK PACKAGE  
(TOP VIEW)  
The devices allow data transmission from the  
A bus to the B bus or from the B bus to the A bus,  
depending on the logic level at the  
direction-control (DIR) input. The output-enable  
(OE) input can be used to disable the device so  
that the buses are effectively isolated.
