AUIRS212(7,71,8,81)S
Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which permanent damage to the device may occur.
These are stress ratings only, functional operation of the device at these or any other condition beyond those
indicated in the “Recommended Operating Condition” is not implied. Exposure to absolute maximum-rated
conditions for extended periods may affect device reliability. All voltage parameters are absolute voltages
referenced to COM unless otherwise stated in the table. The thermal resistance and power dissipation ratings are
measured under board mounted and still air conditions.
