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.
