General Description

This octal bus transceiver is designed for asynchronous two-way communication between data buses.

The control function implementation allows for maximum flexibility in timing.

This 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 levels at the enable inputs (GBA and GAB).
