The ’LV126A devices feature independent line  
drivers with 3-state outputs. Each output is  
disabled when the associated output-enable (OE)  
input is low.

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-sourcing  
capability of the driver.
