The inform ation in this docum ent is based on docum ents issued in April, 1998 at the latest. The infor-
m ation is subject to change w ithout notice. For actual design-in, refer to the latest publications of data
sheet, etc., for the m ost up-date specifications of the device.
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 assum es no responsibility for any errors which m ay ap-
pear in this docum ent.
NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual prop-
erty rights of third parties by or arising from use of a device described herein or any other liability arising from
use of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights or
other intellectual property rights of NEC Corporation or others.
While NEC Corporation has been m aking continuous effort to enhance the reliability of its electronic com-
ponents, the possibility of defects cannot be elim inated entirely. To m inim ize risks of dam age 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
system s, anti-crim e system s, safety equipm ent and m edical equipm ent (not specifically de-
signed for life support)
Specific: Aircrafts, aerospace equipm ent, subm ersible repeaters, nuclear reactor control system s, 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.
