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 malfunctionor
failure of which may cause loss of human life or bodily injury (“Unintended Usage”). Unintended Usage include atomic energy control
instruments, airplane or spaceship instruments, transportation instruments, traffic signal instruments, combustion control instruments,
medical instruments, all types of safety devices, etc.. Unintended Usage of TOSHIBA products listed in this document shall be made
at the customer’s own risk.
