The SN74AHCT1G86 is a single 2-input exclusive-OR gate. The device performs the Boolean function
Y = A ⊕ B or Y = AB + A B in positive logic.

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.
