Stresses beyond those listed as “Absolute Maxim Ratings” may cause permanent damage to the device. These are stress ratings only, any
functional operation of the device at these or any other conditions beyond the those indicated in operations section of the specifications is no
implied. Exposure to absolute maximum ratings for extended periods may affect device reliability.
