description/ordering information  
These octal bus transceivers are designed for asynchronous two-way communication between data buses.  
These devices transmit data from the A bus to the B bus or from the B bus to the A bus, depending upon the  
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.
