SANYO Semiconductor Co.,Ltd. assumes no responsibility for equipment failures that result from using

products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition

ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor Co.,Ltd.

products described or contained herein.

SANYO Semiconductor Co.,Ltd. strives to supply high-quality high-reliability products, however, any and all

semiconductor products fail or malfunction with some probability. It is possible that these probabilistic failures or

malfunction could give rise to accidents or events that could endanger human lives, trouble that could give rise

to smoke or fire, or accidents that could cause damage to other property. When designing equipment, adopt

safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not

limited to protective circuits and error prevention circuits for safe design, redundant design, and structural

design.
