ABSTRACT:
A low power line driving transmission apparatus is described in which TDM signals are transmitted between points over a transmission line comprising a pair of conductors and in which the characteristic impedance of the tranmission line and the source impedance of the transmitters is matched and wherein the input impedance of the receivers is sufficiently high to present an effective open circuit to received signals. Under these conditions the transmitter dissipates power only during logical transitions of the input signals.
