ELECTRICAL CHARACTERISTICS

DYNAMIC ELECTRICAL CHARACTERISTICS

Table 4. Dynamic Electrical Characteristics (continued)

Characteristics noted under conditions 7.0 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.
