Abstract
A receiver circuit includes: a current/voltage conversion circuit which performs a current/voltage conversion based on current which flows through the differential signal lines and outputs voltage signals; a comparator which compares the voltage signals and outputs an output signal; a power-down detection circuit which, when the transmitter circuit transmits a power-down command by current-driving the differential signal lines in a normal transfer mode, detects the transmitted power-down command based on a comparison result from the comparator; and a power-down setting circuit which sets at least one of the current/voltage conversion circuit and the comparator to a power-down mode when the power-down command is detected.
