IR2238Q
Static Electrical Characteristics cont.
VBIAS (VCC, VBS1,2,3) = 15V and TA = 25oC unless otherwise specified. The VIN, VTH and IIN parameters are refer-
enced to VSS and are applicable to all six channels (HOP/HOQ/HON1,2,3 and LOP/LOQ/LON1,2,3). The VO and IO
parameters are referenced to COM and VS1,2,3 and are applicable to the respective output leads: HO1,2,3 and LO1,2,3.
VDESAT and IDESAT parameters are referenced to COM and VS1,2,3
