    Hi,

    Pl advise any circuit or specific IC for Voice multiplexing.
    I have 4 channels of voice signal, each channel has PTT+, PTT-, Tx+, Tx-, RX+ and RX-.
    I need to switch between 4 channels to one output channel which will be connected to HF Radio.
    Output impedance will be 600Ω.

    Please help me with the circuit.

    Thanks in advance.

    regards,
    Surendra
