CAUTION: Stresses 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 sections of this specification is not implied.
NOTE:
4. θJA is measured with the component mounted on an low effective thermal conductivity test board in free air. See Technical Brief 379 for details.
