8.5 Result of exceeding a rating

Measured characteristic

Operating rating

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.
