Note: Do not apply a signal to any pins when it is the output
mode. Damage may result.
All floating (high impedance) bus pins must have their input
levels fixed by means of pull-up or pull-down resistors.

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 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).
Note 1: V
= 0V or High impedance condition

Note 2: High or Low state. Do not exceed I
