Stresses above those listed under Absolute Maximum
Ratings may cause permanent device failure. Function-
ality at or above these limits is not implied. Exposure to
Absolute Maximum Ratings for extended periods may
affect device reliability.
Operating ranges define those limits between which
the functionality of the device is guaranteed.
