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 per-

formed during production and Quality Assurance inspection. Any

blank section in the data column indicates that the specification is

not tested at the specified condition.

Unless otherwise noted, all tests are pulsed; therefore,

Tj = TC = TA.

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.
