STATIC ELECTRICAL CHARACTERISTICS

Table 3. Static Electrical Characteristics

Characteristics noted under conditions 16 V ≤ B+ ≤ 34 V, 0°C ≤ TA ≤ 70°C, and 0°C ≤ TJ ≤ 100°C unless otherwise noted.

Typical values noted reflect the approximate parameter means at TA = 25°C under nominal conditions unless otherwise noted.
