Measured characteristic
Operating rating
Failures in time (ppm)
The likelihood of permanent chip failure increases rapidly as
soon as a characteristic begins to exceed one of its operating ratings.

8.7 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.
