CAUTION: Stresses above those listed in âAbsolute Maximum Ratingsâ 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 speciï¬cation is not implied.
NOTE:
1. θJA is measured with the component mounted on a low effective thermal conductivity test board in free air. (See Tech Brief TB379 for details.).
