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.
NOTES:
1. Only if pin #2 is used to increase current.
2. θJA is measured with the component mounted on an evaluation PC board in free air.
