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 pin.

The thermal resistance and power dissipation ratings are

measured under board mounted and still air conditions.
