Stresses at or above those listed under Absolute Maximum

Ratings may cause permanent damage to the product. This is a

stress rating only; functional operation of the product at these

or any other conditions above those indicated in the operational

section of this specification is not implied. Operation beyond

the maximum operating conditions for extended periods may

affect product reliability.

1 Results are from simulations. The printed circuit board (PCB) is JEDEC

multilayer. Thermal performance for actual applications requires careful

inspection of the conditions in the application to determine whether they

are similar to those assumed in these calculations.
