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.

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 test-

ing actually performed during production and

Quality Assurance inspection. Any blank sec-

tion in the data column indicates that the speci-

fication is not tested at the specified condition.
