description/ordering information  
These octal bus transceivers are designed for asynchronous communication between data buses. The devices  
transmit data 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 the buses are  
effectively isolated.
