A system for communicating between a plurality of nodes in a computer, each node including logic circuitry for transmitting and receiving data. The subject system includes (1) a bus for carrying the data between the nodes (2) a cur-, rent source circuit coupled to the bus for decreasing the transition time of the data transmitted onto the bus and (3) cou-, pling resistors individually coupling the bus to the driver in each node and providing impedance matching between the bus and nodes and permitting driver overlap at the bus so that higher speed and lower power dissipation occurs. In the preferred embodiment, CMOS logic circuitry is utilized and resistors are used to terminate the ends of …
