< Keep safety first in your circuit designs! >
Mitsubishi Electric Corporation puts the maximum effort into
making semiconductor products 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 appropriate measures
such as (1)placement of substitutive, auxiliary circuits, (2)use of
non-flammable material or (3)prevention against any malfunction
or mishap.
