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.
