Specifications shown in boldface are tested on all production units at final electrical test. Results from those tests are used to calculate
outgoing quality levels. All minimum and maximum specifications are guaranteed, although only those shown in boldface are tested on
all production units.

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