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.

LEVEL

TEST PROCEDURE

I

100% production tested at the specified temperature.

II

specified temperatures.

III

QA sample tested only at the specified temperatures.

IV

Parameter is guaranteed (but not tested) by design and characteri-

zation data.

V

Parameter is a typical value for information purposes only.

VI

over specified temperature range.
