*Stresses greater than those listed under "Absolute
ABSOLUTE MAXIMUM RATINGS*
Maximum Ratings" may cause permanent damage to the
device. This is a stress rating only and functional opera-
tion of the device at these or any other conditions above
those indicated in the operation section of this specifica-
tion 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.
