TEST PROCEDURE
100% production tested at the specified temperature.
100% production tested at TA = +25 °C, and sample tested
at the specified temperatures.
QA sample tested only at the specified temperatures.
Parameter is guaranteed (but not tested) by design and
characterization data.
Parameter is a typical value for information purposes only.
100% production tested at TA = +25 °C. Parameter is
guaranteed over specified temperature range.

TEST LEVEL CODES
All electrical characteristics are subject to the following
conditions:
All parameters having min/max specifications are guar-
anteed. The Test Level column indicates the specific
device testing actually performed during production
and Quality Assurance inspection. Any blank section in
the data column indicates that the specification is not
tested at the specified condition.
