ABSTRACT:
A serial data communication system is disclosed. This system includes a plurality of stations which are interconnected by a single clock wire and a single data wire. A master station in the stations includes a transistor push-pull circuit for driving the clock wire to output a clock signal on the clock wire. The clock signal thus has sharp leading and falling edges. The data wire is coupled to wire logic means. A transmitting station transmits each bit of a data signal on the data wire in synchronism with one of leading and falling edges of the associated clock pulse of the clock signal, and a receiving station receives each bit of the data signal in synchronism with the other of leading and falling edges of the associated clock pulse.
