†Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the

device. This is a stress rating only and the functional operation of the device at these or any other conditions

above those indicated in the operation listings of this specification is not implied. Exposure to maximum rating

conditions for extended periods may affect device reliability.
