Description

The 74LVC245A is an octal transceiver 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) pin can be used to disable the device so the buses effectively are isolated.
