TEST LEVEL CODES
All electrical characteristics are subject to the follow-
ing conditions:
All parameters having min/max specifications are
guaranteed. 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.
TEST PROCEDURE
100% production tested at the specified temperature.
100% production tested at T
A
=+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 char-
acterization data.
Parameter is a typical value for information purposes only.
100% production tested at T
A
= +25
