Note 1. 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 in the operational section of the
specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
