ABSTRACT:
A semiconductor integrated circuit that has an output circuit in which an output-stage operating voltage lower than a power supply voltage is applied to an output stage is provided. Even when the power supply voltage is lowered, a sufficient output signal amplitude can be obtained. An increase in circuit scale can be prevented and the power consumption can be reduced. An output-stage operating voltage supply source, including an N-channel MOS transistor having a first threshold voltage, applies an operating voltage lower than a power supply voltage to the output stage of the output circuit. A drive-circuit operating voltage supply source, including an N-channel MOS transistor having a second threshold voltage lower than the first threshold voltage, applies a drive-circuit operating voltage higher than the output-stage operating voltage to a drive circuit.
