Description 

The SN74CBTLV3253 device is a dual 1-of-4 highspeed FET multiplexer and demultiplexer. The low ON-state resistance of the switch allows connections to be made with minimal propagation delay. The select (S0, S1) inputs control the data flow. The FET multiplexers/demultiplexers are disabled when the associated output-enable (OE) input is high. The SN74CBTLV3253 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.
