Abstract
In a conventional equalizer circuit, in an equalizing operation for setting voltages of a wiring pair having a predetermined voltage difference therebetween to be the same, it takes a long time to make the voltages of the wirings in a pair converge to a voltage having an offset with respect to a midpoint voltage of the voltages of the wiring pair after the equalizing operation. According to an equalizer circuit of the present invention, provided is an equalizer circuit (50) which sets the voltages of a first wiring (SAP) and a second wiring (SAN) to be substantially the same and which has a first transistor (N1) connected between the first wiring (SAP) and a first power supply circuit (for example, HVDD−Va) and a second transistor (N2) connected between the first wiring SAP and the second wiring (SAN). The equalizer circuit 50 makes the first transistor (N1) conductive, and then makes the second transistor (N2) conductive.
