IR43x2 Recommended Operating Conditions For proper operation, the device should be used within the recommended conditions below. The Vss and Vsn offset ratings are tested with supplies biased at COM=VN1=VN2, VAA-VSS=9.6V, VCC=12V and VBn-VSn=12V. All voltage parameters are absolute voltages referenced to COM; all currents are defined positive into any lead.
