CAUTION: Stress above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the device
at these or any other conditions above those indicated in the operational section of this specification is not implied.
NOTE:
1. θJA is measured with the component mounted on a highly effective thermal conductivity test board on free air. See Tech Brief TB379 for details
2. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside.
