Absolute Maximum Ratings

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

eters are absolute voltages referenced to COM. The Thermal Resistance and Power Dissipation ratings are measured

under board mounted and still air conditions.
