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 indi-
III
cates the specific device testing actually per-
IV
formed during production and Quality Assur-
ance inspection. Any blank section in the data
V
column indicates that the specification is not
tested at the specified condition.

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.
