Caution If the absolute maximum ratings of even one of the parameters is exceeded even momentarily,

the quality of the product may be degraded. The absolute maximum ratings are therefore values

which, when exceeded, can cause the product to be damaged. Be sure that these values are never

exceeded when using the product.
