Keep safety first in your circuit designs!

•

Renesas Technology Corporation puts the maximum effort into making semiconductor prod-

ucts better and more reliable, but there is always the possibility that trouble may occur with

them. Trouble with semiconductors may lead to personal injury, fire or property damage.

Remember to give due consideration to safety when making your circuit designs, with ap-

propriate measures such as (i) placement of substitutive, auxiliary circuits, (ii) use of non-

flammable material or (iii) prevention against any malfunction or mishap.
