Note:
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 operation listings of this specification are not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
