STATIC ELECTRICAL CHARACTERISTICS
Table 4. Static Electrical Characteristics (continued)
Characteristics noted under conditions 2.7V ≤ V_IN ≤ 5.5V, -20°C ≤ T_A ≤ 85°C, GND = 0V, unless otherwise noted. Typical
values noted reflect the approximate parameter means at T_A = 25°C under nominal conditions, unless otherwise noted.
