    Hi Marc, 

    NCs are not internally connected to any circuitry.

    Normally, NC is connected to ground or the thermal pad as a best practice to improve the thermal performance of the device. If that is not possible connecting it to OUT/IN should not cause any issue due to the lack of connection to any circuitry. 

    Best,
