Caution: Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any parameter.

That is, the absolute maximum ratings are rated values at which the product is on the verge of suffering

physical damage, and therefore the product must be used under conditions that ensure that the absolute

maximum ratings are not exceeded.
