Threshold control
* VDD and Vss are output pins of voltages internally boosted. Connecting a load directly to these pins is not
recommended.
** The standby pin is internally pulled down.
*** Use capacitors with a working voltage of 16 V or higher as C1 through C4. Insert a bypass capasitor about 0.1
to 1 µF between VCC pin to GND pin.
