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 guaranteed. The Test
Level column indicates the specific device test-
ing actually performed during production and
Quality Assurance inspection. Any blank sec-
tion in the data column indicates that the speci-
fication is not tested at the specified condition.
