Texas Instruments  SN74CBTLV3253DE4

The SN74CBTLV3253 device is a dual 1-of-4 high-speed FET multiplexer and demultiplexer.The low ON-state resistance of the switch allows connections to be made with minimal propagationdelay.

The select (S0, S1) inputs control the data flow. The FET multiplexers/demultiplexers aredisabled when the associated output-enable (OE) input is high.

The SN74CBTLV3253 device is fully specified for partial-power-down applications usingIoff. The Ioff feature ensures that damaging currentwill not backflow through the device when it is powered down. The device has isolation during poweroff.
