    Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
    functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
    implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
    NOTES:
    1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
    2. The package thermal impedance is calculated in accordance with EIA/JEDEC Std JESD51.
