Caution
Product quality may suffer if the absolute maximum rating is exceeded for even a single parameter or even
momentarily. That is, the absolute maximuam 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 which ensure that the absolute maximum
ratings are not exceeded.
