STATIC ELECTRICAL CHARACTERISTICS
Table 4. Static Electrical Characteristics
Characteristics noted under conditions 2.7 V ≤ VIN ≤ 5.5 V, -20°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.
