(1) Operation outside the Absolute Maximum Ratings may cause permanent damage to the device. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed  under Recommended Operation Condition.  If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.
