Notes 
1)

 

The information contained herein is subject to change without notice.   

 
2)

 

Although  LAPIS  Semiconductor  is  continuously  working  to  improve  product  reliability  and  quality,  semiconductors  can 
break down and malfunction due to various factors. Therefore, in order to prevent personal injury or fire arising from failure,   
please  take  safety  measures  such  as  complying  with  the  derating  characteristics,  implementing  redundant  and  fire 
prevention  designs,  and  utilizing  backups  and  fail-safe  procedures.  LAPIS  Semiconductor  shall  have  no  responsibility 
for any damages arising out of the use of our Products beyond the rating specified by LAPIS Semiconductor. 

 

3)

 

Examples of application circuits, circuit constants and any other information contained herein are provided only to illustrate 
the  standard  usage  and  operations  of  the  Products.The  peripheral  conditions  must  be  taken  into  account  when  designing 
circuits for mass production. 

 
4)

 

The  technical  information  specified  herein  is  intended  only  to  show  the  typical  functions  of  the  Products  and  examples 
of application circuits for the Products.    No license, expressly or implied, is granted hereby under any intellectual property 
rights or other rights of LAPIS Semiconductor or any third party with respect to the information contained in this document; 
therefore LAPIS Semiconductor shall have no responsibility whatsoever for any dispute, concerning such rights owned by 
third parties, arising out of the use of such technical information. 

 
5)

 

The Products are intended for use in general electronic equipment (i.e. AV/OA devices, communication, consumer systems, 
gaming/entertainment sets) as well as the applications indicated in this document. 

 

6)

 

The Products specified in this document are not designed to be radiation tolerant. 

 

7)

 

For  use  of  our  Products  in  applications  requiring  a  high  degree  of  reliability  (as  exemplified  below),  please  contact  and 
consult  with  a  LAPIS  Semiconductor  representative:  transportation  equipment  (i.e.  cars,  ships,  trains),  primary 
communication equipment, traffic lights, fire/crime prevention, safety equipment, medical systems, servers, solar cells, and 
power transmission systems. 

 
8)

 

Do not use our Products  in applications requiring extremely  high reliability, such as aerospace equipment,  nuclear power 
control systems, and submarine repeaters.   

 

9)

 

LAPIS  Semiconductor  shall  have  no  responsibility  for  any  damages  or  injury  arising  from  non-compliance  with  the 
recommended usage conditions and specifications contained herein.
