Note: Stresses above those  listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

During absolute maximum rating overload conditions (V_IN >V_DD  or V_IN <V_SS ) the voltage on V_DD  pins with respect to ground (V_SS ) must not exceed the values defined by the absolute maximum ratings.
