NEC does not assume any liability for infringement of patents, copyrights or other intellectual property
rights of third parties by or arising from use of a product described herein or any other liability arising
from use of such application. No license, express, implied or otherwise, is granted under any patents,

While NEC has been making continuous effort to enhance the reliability of its products, the possibility
of failures cannot be eliminated entirely. To minimize risks of damage to property or injury to person
arising from a failure in an NEC product, customers must incorporate sufficient safety measures in their
design, such as redundancy, fire-containment and anti-failure features.
NEC products are classified into the following three quality grades:
"Standard"
,
"Special"
,
"Specific"
The
"Specific"
quality grade applies only to applications developed based on a customer designated
"quality assurance program" for a specific application. The recommended applications of a product
depend on its quality grade, as indicated below. Customers must check the quality grade of each
application before using it in a particular application.
Standard:
Computers, office equipment, communications equipment, test and measurement equipment,
audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots
Special:
Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically
designed for life support)
Specific:
Military systems, aircraft, aerospace equipment, submersible repeaters, nuclear reactor control
systems, life support systems (medical equipment, etc.) and any other equipment
The quality grade of this product is
"Standard"
unless otherwise specified in this document. If
customers intend to use this product for applications other than those specified for
"Standard"
quality
grade, they should contact NEC sales representative in advance.

Note1: When designing of the power supply, take the measures for the prevention of surge voltage.
Note2: The power supply lines (VDDB and GNDB) occurs large ripple voltage while luminance control
of LCD lamps. There is the possibility that the ripple voltage produces acoustic noise and signal
wave noise in audio circuit and so on. Put a capacitor (5,000 to 6,000
µ
F) between the power
source lines (VDDB and GNDB) to reduce the noise, if the noise occurred in the circuit.

Note1: The power supply capacity should be more than the fusing current. If the power capacity is less
than the fusing current, the fuse may not blow for a short time, and then nasty smell, smoking and
so on may occur.
