Abstract
A semiconductor integrated circuit for receiving a signal having been propagated through a transmission line, has a control circuit that controls on/off of a first to fourth switching circuits, wherein the control circuit turns off the first switching circuit and the second switching circuit and turns on the third switching circuit and the fourth switching circuit in a test operation mode for measuring a resistance value of the terminator resistor, and the control circuit turns on the first switching circuit and the second switching circuit and turns off the third switching circuit and the fourth switching circuit in a normal operation mode for a normal operation.
