Abstract
A differential signal receiver according to the present invention includes a waveform shaping circuit selectively outputting an upper limit value having a first potential difference from a first power supply potential, and a lower limit value having a second potential difference from the upper limit value, from a first and a second output terminals according to a differential signal input, and an amplifier comparing voltages of the first and the second output terminals and outputting one of a voltage almost the same as the first power supply potential or a voltage almost the same as a second power supply potential.
