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 specication is not implied.
NOTE:
1.
θJA is measured with the component mounted on an evaluation PC board in free air.
