the same time. No do occurrence of the bias from the VH terminal (pin 19) , when there is a period of 8 V or
less in the VCC voltage after previously starting up VCC(O). At this time, there is a possibility of leading to
permanent destruction of the device when the voltage of 17 V or more is impressed to the VCC(O) terminal.
Moreover, when earliness VCC falls more than VCC(O) when falling, it is similar.
