Abstract
An output circuit including an input terminal; an output terminal; a PMOS transistor connected with a positive side of a power voltage and the output terminal; a NMOS transistor connected with a negative side of the power supply voltage and the output terminal; a first inverter, to which a gate voltage of the PMOS transistor is input and which exhibits hysteresis in threshold voltage; and a second inverter, to which a gate voltage of the NMOS transistor is input and which exhibits hysteresis in threshold voltage, wherein an OR logic signal of the input signal and a signal obtained by inverting an output signal from the second inverter is input to a gate of the PMOS transistor, and an AND logic signal of the input signal and a signal obtained by inverting an output signal from the first inverter is input to a gate of the NMOS transistor.
