10 PRECAUTIONS ON MOUNTING
<Arrangement of Signal Lines>
In order to prevent generation of electromag-
netic induction noise caused by mutual induc-
tance, do not arrange a large current signal line
near the circuits that are sensitive to noise such
as the oscillation unit.
When a signal line is parallel with a high-speed
line in long distance or intersects a high-speed
line, noise may generated by mutual interfer-
ence between the signals and it may cause a
malfunction.
Do not arrange a high-speed signal line espe-
cially near circuits that are sensitive to noise
such as the oscillation unit.

<Precautions for Visible Radiation
(when bare chip is mounted)>
Visible radiation causes semiconductor devices
to change the electrical characteristics. It may
cause this IC to malfunction. When developing
products which use this IC, consider the
following precautions to prevent malfunctions
caused by visible radiations.
(1) Design the product and implement the IC on
the board so that it is shielded from visible
radiation in actual use.
(2) The inspection process of the product needs an
environment that shields the IC from visible
radiation.
(3) As well as the face of the IC, shield the back and
side too.
