† NOTICE: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent dam-
age to the device. This is a stress rating only and functional operation of the device at those 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.
