 Note that if a B signal is input when the microcontroller power supply is off (not fixed at 0 V) , the power

supply is provided from the pins, so that incomplete operation may result.

 Note that if the B input is applied during power-on, the power supply is provided from the pins and the

resulting supply voltage may not be sufficient to operate the power-on reset.

 Care must be taken not to leave the B input pin open.

 Sample recommended circuits:

*6: The maximum output current is defined as the peak value of the current of any one of the corresponding pins.

*7: The average output current is defined as the value of the average current flowing over 100 ms at any one of the corresponding pins.

*8: The average total output current is defined as the value of the average current flowing over 100 ms at all of the corresponding pins.

WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current,

temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
