Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. *ESD Ratings ESD Machine Model Protection up to 200 V, Class B ESD Human Body Model Protection up to 2000 V, Class 2 ELECTRICAL CHARACTERISTICS (Vin = 5.0 V, C1 = 3.3 mF, C2 = 3.3 mF, TA = −40°C to 85°C, typical values shown are for TA = 25°C unless otherwise noted.
