*Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress

rating only. Functional operation of the device at these or any other condition above those indicated in the operational sections of

this specification, is not implied. Exposure to Absolute Maximum Ratings for extended periods may affect device reliability.
