Note 2: 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).
