STATIC ELECTRICAL CHARACTERISTICS
Table 4. Static Electrical Characteristics (continued).
Characteristics noted under conditions - VSUP From 5.5 V to 18 V and TJ from -40°C to 125°C, unless otherwise noted. Typical
values noted reflect the approximate parameter means at T_A = 25°C under nominal conditions unless otherwise noted.
