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.
