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 VCC = 5V and TA = 25˚C. Note 5:Ratings apply to ambient temperature at 25˚C. Above this temperature derate N Package 13.16 mW/˚C, and M Package 9.52 mW/˚C. FIGURE 1.
