They are not meant to imply that the device should be operated at these limits. The table of “Electrical Characteristics” provides conditions for actual device operation. Note 2: Unless otherwise specified, all voltages are referenced to ground. Note 3: Unless otherwise specified, Min/Max limits apply across the operating temperature range. All typicals are given for V CC = 5V and T A = 25˚C. Note 4: Ratings apply to ambient temperature at 25˚C. Above this temperature derate SSOP (MEA) Package 10.9 mW/˚C.
