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