 TOSHIBA is continually working to improve the quality and reliability of its products. Nevertheless, semiconductor 
devices in general can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical 
stress. It is the responsibility of the buyer, when utilizing TOSHIBA products, to comply with the standards of 
safety in making a safe design for the entire system, and to avoid situations in which a malfunction or failure of 
such TOSHIBA products could cause loss of human life, bodily injury or damage to property. 
In developing your designs, please ensure that TOSHIBA products are used within specified operating ranges as 
set forth in the most recent TOSHIBA products specifications. Also, please keep in mind the precautions and 
conditions set forth in the “Handling Guide for Semiconductor Devices,” or “TOSHIBA Semiconductor Reliability 
Handbook” etc.. 
 The TOSHIBA products listed in this document are intended for usage in general electronics applications 
(computer, personal equipment, office equipment, measuring equipment, industrial robotics, domestic appliances, 
etc.). These TOSHIBA products are neither intended nor warranted for usage in equipment that requires 
extraordinarily high quality and/or reliability or a malfunction or failure of which may cause loss of human life or
