Terminology and guidelines
3.1 Definition: Operating requirement
An
operating requirement
is a specified value or range of values for a technical
characteristic that you must guarantee during operation to avoid incorrect operation and
possibly decreasing the useful life of the chip.
3.1.1 Example
This is an example of an operating requirement, which you must meet for the
accompanying operating behaviors to be guaranteed:
Symbol

3.2 Definition: Operating behavior
An
operating behavior
is a specified value or range of values for a technical
characteristic that are guaranteed during operation if you meet the operating requirements
and any other specified conditions.
3.2.1 Example
This is an example of an operating behavior, which is guaranteed if you meet the
accompanying operating requirements:
