*Stresses greater than those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device. This is
a stress rating only and functional operation of the device at
these or any other conditions above those indicated in the
operation section of this specification is not implied. Exposure
to absolute maximum rating conditions for extended periods
may affect reliability.
** Junction temperature depends upon package type, cycle
time, loading, ambient temperature and airflow.
