3.7 Guidelines for ratings and operating requirements
Follow these guidelines for ratings and operating requirements:
Never exceed any of the chip’s ratings.
During normal operation, don’t exceed any of the chip’s operating requirements.
If you must exceed an operating requirement at times other than during normal
operation (for example, during power sequencing), limit the duration as much as
possible.
3.8 Definition: Typical value
A typical value is a specified value for a technical characteristic that:
Lies within the range of values specified by the operating behavior
Given the typical manufacturing process, is representative of that characteristic
during operation when you meet the typical-value conditions or other specified
conditions
Typical values are provided as design guidelines and are neither tested nor guaranteed.
