Caution Even if one of the parameters exceeds its absolute maximum rating even momentarily, the quality
of the product may be degraded. The absolute maximum rating therefore specifies the upper or
lower limit of the value at which the product can be used without physical damages. Be sure not
to exceed or fall below this value when using the product.
