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, all currents are defined positive into any lead.
The thermal resistance and power dissipation ratings are measured under board mounted and still air
conditions.
Recommended Operating Conditions
For proper operation the device should be used within recommended conditions.
