description/ordering information  
The SN74CBTLV3126 quadruple FET bus switch features independent line switches. Each switch is disabled  
when the associated output-enable (OE) input is low.  
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 GND through a  
pulldown resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
