Unless otherwise noted, the absolute maximum ratings are specified over operating conditions. Stresses beyond those listed under
Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
