No part of this document may be copied or reproduced in any form or by any means without the prior written

consent of NEC Corporation. NEC Corporation assumes no responsibility for any errors which may ap-

NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual prop-

While NEC Corporation has been making continuous effort to enhance the reliability of its electronic com-

ponents, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to

persons or property arising from a defect in an NEC electronic component, customer must incorporate suffi-

cient safety measures in its design, such as redundancy, fire-containment, and anti-failure features.

NEC devices are classified into the following three quality grades:

“Standard”, “Special”, and “Specific”. The Specific quality grade applies only to devices developed based on a

customer designated “quality assurance program” for a specific application. The recommended applications of

a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device

before using it in a particular application.

Standard: Computers, office equipment, communications equipment, test and measurement equipment, au-

dio and visual equipment, home electronic appliances, machine tools, personal electronic equip-

ment 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 de-

signed for life support)

Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, Iife

support systems or medical equipment for life support, etc.

The quality grade of NEC devices is “Standard” unless otherwise specified in NEC's Data Sheets or Data Books.

If customers intend to use NEC devices for applications other than those specified for Standard quality grade,

they should contact NEC sales representative in advance.

Anti-radioactive design is not implemented in this product.
