Cautions 1. Do not simultaneously short multiple outputs.
2. 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. The ratings and
conditions displayed in DC Characteristics and AC Characteristics in this section indicate the
ranges in which normal operation and product quality can be guaranteed.
