An output circuit includes first to fourth transistors, first and second constant current units, and a differential pain The gates of the first and second transistors are supplied with two input signals, respectively. The drain of the first transistor is coupled to the drain of the third transistor and the gate of the fourth transistor. The drain of the second transistor is coupled to the gate of the third transistor and the drain of the fourth transistor. The first constant current unit is coupled to the sources of the third and fourth transistors. The differential pair includes two transistors, and the gates of the two transistors are coupled to the drains of the first and second transistors, respectively. The second constant current unit is coupled to the sources of the two transistors. Two output signals are output from two nodes respectively corresponding to the drains of the two transistors.
