Note: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent
damage of 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 longer
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.
