† Stresses beyond those listed under “absolute maximum ratings” can cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods can affect device reliability.
NOTE 1: All voltage values are with respect to GND.
