STATIC ELECTRICAL CHARACTERISTICS

STATIC ELECTRICAL CHARACTERISTICS (continued)

Characteristics noted under conditions 4.75 V ≤ VIO ≤ 5.25 V, 13 V ≤ VB+ ≤ 32 V, 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.
