Absolute Maximum Ratings

The “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 defines the

conditions for actual device operation.
