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

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 disable the device so that the  
buses are effectively isolated.
