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. operating
temperature/current/voltage, etc.) are within the absolute maximum ratings.
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).
