Note 1: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage a
significant change in temperature, etc.) may significantly reduce the reliability of this product
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please consult 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) when designing in order to ensure the appropriate reliability.
