  • Multiplexing circuitry for time sharing a common conductor
    Patent number: 4010385
    Abstract: A multiplexing circuit includes a plurality of passive circuit networks having a multiphase clocking signal associated therewith to selectively enable transmission of information signals over a common conductor. Each passive circuit network is enabled during a distinct phase of the multiphase clocking signal to provide a distinct circuit path for transmission of information signals with each distinct path including the common conductor. The enabling of the passive circuit networks by the multiphase clocking signal allows time sharing of the common conductor.
