STATIC ELECTRICAL CHARACTERISTICS
Table 3. Static Electrical Characteristics (continued)
Characteristics noted under conditions 5.5 V ≤ VSUP ≤ 18 V, -40°C ≤ TA ≤ 125°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.
