Abstract
A system wherein multiple sources of data each have drivers for transmitting data to a common system bus. The drivers are each managed by individual enabling logic which is controlled by a flip-flop driven by a clock. Thus no driver can connect and drive data onto the bus until one clock period after the previously connected driver has been disabled and disconnected from the bus.
