Absolute Maximum Ratings
Note 1: Absolute Maximum Ratings: are those values beyond which the safety of the device cannot be guaranteed. The device
should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed
at the absolute maximum ratings. The "Recommended Operating Conditions" table will define the conditions for actual device
operation.
