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. Absolute maximum ratings are limiting values, applied individually, beyond which the serviceability of the circuit may be impaired. Functional
operability under any of these conditions is not necessarily implied.

for the QFN package is measured in free air with the component mounted on a high effective thermal conductivity test board with direct
attach features including conductive thermal vias. See Tech Brief TB379 and TB389 for additional information and board layout consideration
