1. A multichannel switch integrated circuit comprising:
a multichannel switch circuit provided with three or more switch circuitries, each including an output transistor that outputs an output signal through an output terminal, an overcurrent detection circuit that detects a detection current according to a current flowing through the output transistor, and a diode that receives the detection current at an anode of the diode; and
a first common test terminal connected to a cathode of the diode provided in odd-numbered switch circuitries of the multichannel switch circuit; and
a second common test terminal connected to a cathode of the diode provided in an even-numbered switch circuitry of the multichannel switch circuit.
