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).
