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 guaran-
teed over specified temperature range.
TEST LEVEL CODES
All electrical characteristics are subject to the
following conditions: All parameters having
min/max specifications are guaranteed. The
Test Level column indicates the specific
device testing actually performed during pro-
duction and Quality Assurance inspection.
Any blank section in the data column indi-
cates that the specification is not tested at the
specified condition.
