Absolute Maximum Ratings
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 condition beyond those indicated in the specifications is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. The thermal resistance
and power dissipation ratings are measured under board mounted and still air conditions. Ambient temperature (TA) is 25°C, unless
otherwise specified.
