21.1 Absolute Maximum Ratings
The absolute maximum ratings are the limits to which the device can be subjected without permanently
damaging the device and are stress ratings only. Device reliability may be adversely affected by exposure
to absolute-maximum ratings for extended periods. Functional operation of the device at the absolute
maximum ratings or any other conditions beyond the recommended operating conditions is not implied.
