According to one embodiment, a semiconductor integrated circuit includes first to six transistors and a constant current source circuit. The first and second transistors form a current mirror circuit connected to a first power source node. The third and fourth transistors form a differential pair circuit. The third and fourth transistors receive first and second external signals at their gates, respectively. The constant current source circuit has one end connected to source terminals of the third and fourth transistors, and the other end connected to a second power source node. The fifth and sixth transistors form a current pathway between a common gate node of the first and second transistors and the constant current source circuit. The gate of fifth transistor is connected to a signal output node. The gate of sixth transistor receives a signal of logic opposite to a signal to be obtained at the signal output node. |
