† 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.
