MULTIPLEXER FOR VOLTAGE MEASUREMENT AND VOLTAGE MEASURING UNIT INCLUDING THE SAME

摘要

A multiplexer for voltage measurement includes: a first switch disposed on a first channel extending between at least one high-voltage input terminal and an output terminal; a plurality of second switches respectively disposed on second channels each extending between each of input terminals other than the high-voltage input terminal and the output terminal; and a third switch disposed between a group of the plurality of second switches and an output terminal side end of the first switch. Each of the first switch and the third switch is configured to operate even by a voltage higher than a power supply voltage.
