TEST LEVEL CODES
All electrical characteristics are subject to the
following conditions:
All parameters having min/max specifications
are guaranteed. The Test Level column indi-
cates the specific device testing actually per-
formed during production and Quality Assur-
ance 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 characteri-
zation data.
Parameter is a typical value for information purposes only.
100% production tested at T
A
= +25 °C. Parameter is guaranteed
over specified temperature range.
