Stresses above those listedunder âAbsolute Maximum Ratingsâ may cause permanent damage to the device. This is a stress rating only and functional
operation ofthe device atthese or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to
absolute maximum ratingconditions for external periods may affect device reliability.
* Allvoltage values are referred to VSS pin voltage.
