The device should not be operated at these limits. The parametric values defined in the Electrical Input Voltage 7V Characteristics tables are not guaranteed at the absolute maximum ratings. The Recommended Operating Conditions table will define the conditions Operating Free Air Temperature Range 0C to +70C for actual device operation.
