Table 4. Dynamic Electrical Characteristics
Characteristics noted under conditions 21 V ≤ VVB+ ≤ 42 V, TA = 10°C to 55°C, TJ max = 135°C, VCC = 5.25 V max unless
otherwise noted. Typical values noted reflect the approximate parameter mean at TA = 25°C under typical conditions unless
otherwise noted.
