† Stresses beyond 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 beyond those indicated in the “recommended operating conditions” section of

this specification is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE 1: All voltage values are with respect to GND.
