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, all currents are defined positive into any lead. The thermal resistance

and power dissipation ratings are measured under board mounted and still air conditions.
