Abstract
A half-matching type transceiver circuit which only requires a reduced area for mounting. A coupling transformer has a primary winding with one end and the other end connected to balanced transmission lines, and a secondary winding with one end and the other end connected to output terminals of first and second tristate buffers, respectively. These tristate buffers are supplied at their respective input terminals with a high potential driving pulse signal corresponding to information data at shifted timings to generate a ternary transmission pulse signal on the balanced transmission lines.
