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.
Unless otherwise noted, all tests are pulsed
tests; therefore, TJ = TC = TA.
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.
