STATIC ELECTRICAL CHARACTERISTICS
Table 3. Static Electrical Characteristics
Characteristics noted under conditions 16 V ≤ B+ ≤ 34 V, 0°C ≤ T_A ≤ 70°C, and 0°C ≤ T_J ≤ 100°C unless otherwise noted.
Typical values noted reflect the approximate parameter means at T_A = 25°C under nominal conditions unless otherwise noted.
