Abstract
A transmission circuit includes a current output circuit that outputs a current to a first node, a first switch element provided between the first node and a first signal line, and a second switch element provided between the first node and a second signal line. When a transmission signal is at a first logic level, the first switch element is ON and the second switch element is OFF. When the transmission signal is at a second logic level, the first switch element is OFF and the second switch element is ON. The current output circuit outputs a second current in an n-bit period after the logic level of the transmission signal is inverted, and outputs a first current after the n-bit period.
