Stresses beyond those 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 beyond those indicated under
recommended operating conditions
is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
