† NOTICE: 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 listings of this specification is not implied. Exposure to Absolute Maximum Rating
conditions for extended periods may affect device reliability.
