Note:

Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or

even destruction.

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 and the operating ranges.

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).
