TEST LEVEL CODES

TEST LEVEL TEST PROCEDURE

All electrical characteristics are subject to the

I

following conditions:

II

All parameters having min/max specifications

are guaranteed. The Test Level column indicates

the specific device testing actually performed

III

during production and Quality Assurance

IV

inspection. Any blank section in the data column

indicates that the specification is not tested at

V

the specified condition.

VI

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.
