A differential communication circuit includes: a first switch in between a signal line and a power source, a second switch in between a signal line and a ground, a third switch in between the signal line and the ground, a fourth switch in between the signal line and the power source, first and second drivers respectively driving the first and second switches, and third and fourth drivers respectively driving the third and fourth switches OFF to ON at an ON to OFF timing of the first and second switches, for setting an ON period of the third and fourth switches to be shorter than a one-bit width in a communication signal and enabling a stable signal level determination while reducing power consumption of the differential communication circuit.
