The SN74LVCC3245ADW is an Octal Bus Transceiver with adjustable output voltage and 3-state outputs. The SN74LVCC3245A 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 device so the buses are effectively isolated. The control circuitry (DIR, OE\) is powered by VCCA.
