APPLICATION NOTES
1)
2)
3)
Do not apply a signal to any bus terminal when it is in the
output mode. Damage my result.
All floating (high impedance) bus terminals must have their
input levels fixed by means of pull up or pull down resistors or
bus terminator IC’s such as the TOHSIBA TC40117BP.
A parasitic diode is formed between the bus and Vcc terminals.
Therefore bus terminal can not be used to interface 5V to 3V
systems directly

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 3: CPD is defined as the value of the internal equivalent capacitance which is calucurated from the operating
current consumption without load.
Average iperating current can be obtained by the equation:
ICC (opr) = CPD･VCC･fIN ICC/2 (per bit)
