Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

1 Results are from simulations. PCB is JEDEC multilayer. Thermal performance
for actual applications requires careful inspection of the conditions in the
application to determine if they are similar to those assumed in these
calculations.
