Absolute Ratings: Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are
stress ratings only. The functional operation of the device at those or any other conditions beyond those indicated under "recommended
operating conditions" is not implied. Exposure to conditions outside the "recommended operating conditions" for any extended period of time
may adversely impact device reliability and result in failures not covered by warranty.
