TEXAS INSTRUMENTS SN74LVC245A OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS Manual

The SN74LVC245A is an octal bus transceiver designed for 1.65-V to 3.6-V VCC operation. 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 effectively are isolated.
