Abstract
A circuit device includes: a transmitting circuit that performs transmission of a signal by current-driving signal lines in a transmission period; a receiving circuit that receives a signal that a transmitting circuit of a communication partner has transmitted by current-driving the signal lines, in a reception period that is different from the transmission period; and terminating resistor circuits that can be connected to the signal lines, and whose resistance value in the transmission period is set to a value that is smaller than a resistance value in the reception period.
