7 / 18 page  © 2010 Fairchild Semiconductor Corporation www.fairchildsemi.com FAN7389 • Rev. 1.0.0 7 Electrical Characteristics VBIAS (VDD, VBS1,2,3) = 15.0V and TA = 25°C unless otherwise specified. The VIN and IIN parameters are referenced to COM and are applicable to all six channels. The VO and IO parameters are referenced to VS1,2,3 and COM and are applicable to the respective output leads: HO1,2,3 and LO1,2,3. The VDDUV parameters are referenced to COM. The VBSUV parameters are referenced to VS1,2,3. Symbol Parameter Conditions Min. Typ. Max.
