Octal Bus Transceivers (with three-state outputs)

REJ03D0464–0300

Rev.3.00

Jul.15.2005

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.
