Note 1:
Limits are guaranteed by 100% testing, sampling, or correlation with worst case test conditions.
ABSOLUTE MAXIMUM RATINGS
Absolute maximum ratings are those values beyond which
the device could be permanently damaged. Absolute
maximum ratings are stress ratings only and functional
device operation is not implied.
