(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum
Ratings do not imply functional operation of the device at these or any other conditions beyond those listed
under Recommended Operating Conditions. 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.
