NOTICE: This data sheet contains information on products in the
sampling and initial production phases of development. The
specifications are subject to change without notice. Verify with
your local Intel Sales office that you have the latest data sheet
before finalizing a design.
WARNING: Stressing the device beyond the ``Absolute
Maximum Ratings'' may cause permanent damage.
These are stress ratings only. Operation beyond the
``Operating Conditions'' is not recommended and ex-
tended exposure beyond the ``Operating Conditions''
may affect device reliability.
