Abstract:
The highest voltage of a power supply voltage, a ground potential, and a signal voltage is output as a selection voltage from a terminal on the output side. In this case, terminals on the input side and the terminal on the output side are connected to each other through MOS transistors in the ON state. Therefore, it is possible to suppress a voltage drop due to a parasitic diode of each MOS transistor.
