Abstract
A differential communication driver circuit includes a drive unit that drives differential signal lines connected via capacitors by a source current and a sink current. When a noise detection unit detects that in-phase noise is applied to the differential signal lines, a drive assisting unit maintains an amplitude of a differential signal output to the differential signal lines by increasing a current drive capability of the sink current.
