In a hysteresis characteristic input circuit, first and second resistors are connected in parallel between a first power supply terminal and a connection point, and first and second MOS transistors are connected in parallel between the connection point and a second power supply terminal and are controlled by an input voltage. An inverter has an input connected to the connection point and an output adapted to generate an output voltage. A first switching element is connected in series to the second resistor, and a second switching element is connected in series to the second MOS transistor. The first and second switching elements are complementarily controlled by the output voltage.
