Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device.These ratings are stress
specifications only and functional operation of the device at these or any other conditions above those listed in the operational
sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect product
reliability.
