This octal bus transceiver is designed for synchronous two-way communication between data buses. The control
function implementation minimizes external timing requirements. The device allows data transmission from the A bus
to the B bus or from the B bus to the A bus depending upon the logic level at the direction control (DIR) input. The
enable input (G) can be used to disable the device so that the buses are effectively isolated.
