There is no single/low cost/no control chip that does 3 channel 1-4.  Each output has to have it's own buffer and you can drive the 4 butters of one channel with 1 input.

You might look at a MAX4022,  https://www.analog.com/media/en/technical-documentation/data-sheets/MAX4014-MAX4022.pdf.

One chip can implement with good design a single channel 1-4 buffer,  3 chips would be able to handle your sources.

Also might check out AN57   www.analog.com/.../an57fa.pdf

If you come up  with a schematic, we can review it.

  • I need single input to 4 output buffer. But it is for video signals
