Absolute Maximum Ratings

Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage

parameters are absolute voltages referenced to COM=VN1=VN2; all currents are defined positive into any lead.

The Thermal Resistance and Power Dissipation ratings are measured under board mounted and still air

conditions.
