EXPLANATION OF TEST LEVELS

Test Level

I

– 100% production tested.

II – 100% production tested at +25

°C, and sample tested at

specified temperatures. AC testing done on sample basis.

III – Sample tested only.

IV – Parameter is guaranteed by design and characterization

testing.

V – Parameter is a typical value only.

VI – All devices are 100% production tested at +25

°C. 100%

production tested at temperature extremes for extended

temperature devices; guaranteed by design and character-

ization testing for industrial devices.
