description/ordering information  
The SN74CBTLV3253 is a dual 1-of-4 high-speed FET multiplexer/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.  
This device is fully specified for partial-power-down applications using I . The I feature ensures that  
off  
off  
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 V  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
