• The value of the limiting resistor should be set to a value at which the current to be input to the microcontroller pin
when the HV (High Voltage) signal is input is below the standard value, irrespective of whether the current is transient
current or stationary current.
• When the microcontroller drive current is low, such as in low power consumption modes, the HV (High Voltage)
input potential may pass through the protective diode to increase the potential of the V
CC pin, affecting other devices.
• If the HV (High Voltage) signal is input when the microcontroller power supply is off (not fixed at 0 V), since power
is supplied from the pins, incomplete operations may be executed.
• If the HV (High Voltage) input is input after power-on, since power is supplied from the pins, the voltage of power
supply may not be sufficient to enable a power-on reset.
• Do not leave the HV (High Voltage) input pin unconnected.
• Example of a recommended circuit:
WARNING: Semiconductor devices may be permanently damaged by application of stress (including, without
limitation, voltage, current or temperature) in excess of absolute maximum ratings.
Do not exceed any of these ratings.
