Product Summary

The SN74LVC245ADWis an octal BUS transceiver with 3-state outputs. The SN74LVC245A 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 SN74LVC245ADW so the bus effectively is isolated.
