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:

1.

JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
