Recommended Operating Conditions
For proper operation the device should be used within the recommended conditions.
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.
