The information in this document is current as of July, 2003. The information is subject to change  
without notice. For actual design-in, refer to the latest publications of NEC's data sheets or data  
books, etc., for the most up-to-date specifications of NEC semiconductor products. Not all products  
and/or types are available in every country. Please check with an NEC sales representative for  
availability and additional information.  
No part of this document may be copied or reproduced in any form or by any means without prior  
written consent of NEC. NEC assumes no responsibility for any errors that may appear in this document.  
NEC does not assume any liability for infringement of patents, copyrights or other intellectual property rights of  
third parties by or arising from the use of NEC semiconductor products listed in this document or any other  
liability arising from the use of such products. No license, express, implied or otherwise, is granted under any  
patents, copyrights or other intellectual property rights of NEC or others.  
Descriptions of circuits, software and other related information in this document are provided for illustrative  
purposes in semiconductor product operation and application examples. The incorporation of these  
circuits, software and information in the design of customer's equipment shall be done under the full  
responsibility of customer. NEC assumes no responsibility for any losses incurred by customers or third  
parties arising from the use of these circuits, software and information.  
While NEC endeavours to enhance the quality, reliability and safety of NEC semiconductor products, customers  
agree and acknowledge that the possibility of defects thereof cannot be eliminated entirely. To minimize  
risks of damage to property or injury (including death) to persons arising from defects in NEC  
semiconductor products, customers must incorporate sufficient safety measures in their design, such as  
redundancy, fire-containment, and anti-failure features.  
NEC semiconductor products are classified into the following three quality grades:  
"Standard", "Special" and "Specific". The "Specific" quality grade applies only to semiconductor products  
developed based on a customer-designated "quality assurance program" for a specific application. The  
recommended applications of a semiconductor product depend on its quality grade, as indicated below.  
Customers must check the quality grade of each semiconductor product 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": Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life  
support systems and medical equipment for life support, etc.  
The quality grade of NEC semiconductor products is "Standard" unless otherwise expressly specified in NEC's  
data sheets or data books, etc. If customers wish to use NEC semiconductor products in applications not  
intended by NEC, they must contact an NEC sales representative in advance to determine NEC's willingness  
to support a given application.  
(Note)  
(1) "NEC" as used in this statement means NEC Corporation, NEC Compound Semiconductor Devices, Ltd.  
and also includes its majority-owned subsidiaries.  
(2) "NEC semiconductor products" means any semiconductor product developed or manufactured by or for  
NEC (as defined above).

CLASS lllb LASER PRODUCT  
A laser beam is emitted from this diode during operation.  
Warning Laser Beam  
Caution GaAs Products  
The laser beam, visible or invisible, directly or indirectly, may cause injury to the eye or loss of  
eyesight.  
• Do not look directly into the laser beam.  
• Avoid exposure to the laser beam, any reflected or collimated beam.  
This product uses gallium arsenide (GaAs).  
GaAs vapor and powder are hazardous to human health if inhaled or ingested, so please observe  
the following points.  
• Follow related laws and ordinances when disposing of the product. If there are no applicable laws  
and/or ordinances, dispose of the product as recommended below.  
1. Commission a disposal company able to (with a license to) collect, transport and dispose of  
materials that contain arsenic and other such industrial waste materials.  
2. Exclude the product from general industrial waste and household garbage, and ensure that the  
product is controlled (as industrial waste subject to special control) up until final disposal.  
• Do not burn, destroy, cut, crush, or chemically dissolve the product.  
• Do not lick the product or in any way allow it to enter the mouth.  
A glass-fiber is attached on the product. Handle with care.  
Caution Optical Fiber  
• When the fiber is broken or damaged, handle carefully to avoid injury from the damaged part  
or fragments.
