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..

Notice
The circuits and measurements contained in this document are given only in the context of as examples of
applications for these products.
Moreover, these example application circuits are not intended for mass production, since the high-frequency
characteristics (the AC characteristics) of these devices will be affected by the external components which the
customer uses, by the design of the circuit and by various other conditions.
It is the responsibility of the customer to design external circuits which correctly implement the intended
application, and to check the characteristics of the design.
TOSHIBA assume no responsibility for the integrity of customer circuit designs or applications.
