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.Recommended Operating ConditionsElectrical Characteristicsover recommended operating free air temperature range.
