(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress
ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under
Recommended Operating Conditions . Exposure to absolute-maximum-rated conditions for extended periods may affect device
reliability.
8.2 ESD Ratings
