Claim 10:
11. An apparatus comprising:
a multi-input comparator (MIC) configured to receive, in a half-duplex mode of operation detecting a plurality of mutually orthogonal sub-channels, a set of at least four input signals and to responsively generate a respective linear combination of the set of at least four input signals to detect an orthogonal sub-channel of a plurality of mutually orthogonal sub-channels, each input signal received via a respective wire of a multi-wire bus;
a set of T-switches driven by a set of corresponding low-impedance switch drivers configured to initiate a full-duplex mode of operation by selectively disconnecting a pair of wires of the multi-wire bus from the MIC responsive to corresponding enable signals provided via low-impedance enable signal paths in the corresponding low-impedance switch drivers;
a set of drivers configured to transmit a differential outbound signal in the full-duplex mode on the selectively disconnected pair of wires;
the low impedance switch drivers configured to shunt capacitively-coupled interference signals from the differential outbound signal on the pair of wires in the full-duplex mode of operation via the low-impedance enable signal paths; and
the MIC configured to generate a differential output in the full-duplex mode of operation by forming a comparison of inbound signals received on at least two remaining wires of the of the multi-wire bus connected to the MIC in the full-duplex mode of operation.
