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.

VI

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.
