Use within recommended operating conditions.
Use at DC voltage (current).
The +B signal should always be applied by connecting a limiting resistor between the +B signal and the
microcontroller.
The value of the limiting resistor should be set so that the current input to the microcontroller pin does not
exceed rated values at any time regardless of instantaneously or constantly when the +B signal is input.
Note that when the microcontroller drive current is low, such as in the low power consumption modes, the
+B input potential can increase the potential at the VCC pin via a protective diode, possibly affecting other
devices.
Note that if the +B signal is input when the microcontroller is off (not fixed at 0V), since the power is supplied
through the pin, the microcontroller may operate incompletely.
Do not leave +B input pins open.
Sample recommended circuit
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.
