Note: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. Stresses listed as the "Absolute Maximum Ratings" will cause permanent damage to the device.
3. The device is not guaranteed to function when it’s beyond its operating conditions.
