The output is disabled when the output-enable (OE) input is low. When OE is high, true data is passed from the A input to the Y output. 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.
