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).
