A peak level detection circuit provided with a peak holding unit used for determining the threshold level for discrimination of the logics "1" and "0" of the received data from the peak level of the received data signals, wherein even if after a first input pulse train with a peak level of Vin1 is received, a second input pulse train having a peak level of Vin2 lower than Vin1 is received, it is made possible to immediately discriminate the logics "1" and "0" of the second input pulse train by detecting the appearance of the second input pulse train, then immediately pulling down the Vin1 which is held.
