SN74CBTLV3245APWR .

The SN74CBTLV3245APWR is an octal FET Bus Switch features low ON-state resistance which allows connections to be made with minimal propagation delay. The device is organized as one 8-bit switch. When OE\ is low, the 8-bit bus switch is on and port A is connected to port B. When OE\ is high, the switch is open and the high-impedance state exists between the two ports. This device is fully specified for partial-power-down applications using Ioff. The Ioff feature ensures that damaging current will not backflow through the device when it is powered down. The device has isolation during power off. To ensure the high-impedance state during power up or power down, OE\ should be tied to VCC through a pull-up resistor, the minimum value of the resistor is determined by the current-sinking capability of the driver.
