STATIC AND DYNAMIC ELECTRICAL CHARACTERISTICS
Table 2. Electrical Characteristics
Characteristics noted under conditions 9.0 V ≤ VIN ≤ 18 V, - 40°C ≤ TA ≤ 85°C, GND = 0 V, unless otherwise noted. Typical
values noted reflect the approximate parameter means at TA = 25°C under nominal conditions, unless otherwise noted.
