The is an octal Bus Transceiver designed for asynchronous two-way 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 upon the level at the direction control DIR input. The enable input G\\ can be used to disable the device so the buses are effectively isolated.
