Note - The device is not guaranteed to function outside its operating rating. Stresses listed under Absolute Maximum
Ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions outside those listed in the operational sections of the specification is not
implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability.
