ELECTRICAL CHARACTERISTICS

STATIC ELECTRICAL CHARACTERISTICS

Table 3. Static Electrical Characteristics (continued)

Characteristics noted under conditions 3.0 V ≤ VIN ≤ 6.0 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.
