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.
