The SN74AVC32T245 is designed for asynchronous communication between data buses. The device transmits

data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the

direction-control (DIR) input. The output-enable (OE) input can be used to disable the outputs so the buses are

effectively isolated.

The SN74AVC32T245 is designed so that the control pins (1DIR, 2DIR, 3DIR, 4DIR, 1OE, 2OE, 3OE, and 4OE)
