< 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.
