TEST LEVEL CODES

All electrical characteristics are subject to the

following conditions:

All parameters having min/max specifications are

guaranteed. The Test Level column indicates the

specific device testing actually performed during

production and Quality Assurance inspection. Any

blank section in the data column indicates that the

specification is not tested at the specified

condition.

TEST PROCEDURE

100% production tested at the specified temperature.

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.

guaranteed over specified temperature range.
