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

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