ABSTRACT:
In order to prevent malfunction due to fluctuations in signal level, a terminating resistor circuit includes terminating resistors the connections whereof to an input/output terminal are capable of being turned on and off, whereby a Thevenin termination is formed. A control circuit exercises control so as to temporally stagger on/off timings of respective ones of the terminating resistors.
