IR2108(4) (S) & (PbF)

Dynamic Electrical Characteristics

VBIAS (VCC, VBS) = 15V, VSS = COM, CL = 1000 pF, TA = 25°C, DT = VSS unless otherwise specified.

Static Electrical Characteristics

VBIAS (VCC, VBS) = 15V, VSS = COM, DT= VSS and TA = 25°C unless otherwise specified. The VIL, VIH and IIN

parameters are referenced to VSS/COM and are applicable to the respective input leads: HIN and LIN. The VO, IO and Ron

parameters are referenced to COM and are applicable to the respective output leads: HO and LO.
