STATIC ELECTRICAL CHARACTERISTICS
Table 3. STATIC ELECTRICAL CHARACTERISTICS (continued)
Characteristics noted under conditions 4.75V ≤ VIO ≤ 5.25V, 13V ≤ VB+ ≤ 32V, and 0°C ≤ TJ ≤ 105°C, unless otherwise noted.
Typical values noted reflect the approximate parameter mean at TA = 25°C under nominal conditions, unless otherwise noted.
