† _{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.
