Abstract
A digital signal input device has a first input terminal and a second input terminal, a charging circuit connected between the first input terminal and the second input terminal, and a digital signal detection unit that outputs a digital signal of a logical value corresponding to a level of a charging voltage to an internal circuit. A pulse control unit generates a pulse signal having a fixed period using designated pulse width and pulse period. A switching element is provided between the charging circuit and the first input terminal or the second input terminal, which controls a period of applying a DC voltage to the charging circuit using a pulse width of the pulse signal.
