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 external periods may affect device reliability.
