This octal bus transceiver is designed for1.65Vto3.6V Vcc operation. 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(DlR)input.Theoutput- enable(OE)input can be used to disable the device so the buses effectively are isolated.
