There is provided a signal transmission system, wherein when a control signal which puts an output terminal of an output circuit (12A) into a high-impedance state is supplied to the output circuit (12A) and an input circuit (14A), power is fed to the input circuit (12A) to operate it and, at the same time, power-feeding to the output circuit (12A) is stopped; and when the control signal is not supplied to the output circuit (12A) nor the input circuit (14A), power is fed to the output circuit (12A) to operate it and, at the same time, power-feeding to the input circuit (12A) is stopped. Also, a signal of an expected value of the output circuit (12A) based on the control signal is generated from an OR circuit (45). <IMAGE> |
