This is a stress rating only and functional operation on the
device at these or any other conditions above those indicated
in the operational sections 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. See the Application
Information section at the end of this datasheet for more infor-
mation.
