(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.
(2)
Higher temperatures may be applied during board soldering according to the current JEDEC J-STD-020 specification with peak reflow
temperatures not higher than classified on the device label on the shipping boxes or reels.
