† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:

1. All voltage values are with respect to the network ground terminal.

2. For operation above 25

°C free-air temperature, derate linearly at the rate of 16.6 mW/°C.

3. For operation above 25

°C case temperature, derate linearly at the rate of 71.4 mW/°C. Due to variations in individual device electrical

characteristics and thermal resistance, the built-in thermal overload protection may be activated at power levels slightly above or

below the rated dissipation.
