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.
