Note 1:

Note 4:

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).

Output in OFF state

High or low state. IOUT absolute maximum rating must be observed.
