Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress ratingonly 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 external periods may affect device reliability.
* All voltage values are referred to VSS pin voltage.
