Note: Using continuously under heavy loads (e.g. the application of high
temperature/current/voltage and the significant change in

temperature, etc.) may cause this product to decrease in the
reliability significantly even if the operating conditions (i.e.

Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
