74LVT640PW

3.3 V Octal transceiver with direction pin; inverting; 3-state

The 74LVT640 is an 8-bit inverting transceiver with 3-state outputs. The device features an output enable (OE) and send/receive (DIR) for direction control. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs
