Single pole triple throw analog passthrough
There are many 4:1 analog mux parts that will meet your requirement, in both the CD4xxx series and DGxxx series.  Analog Devices, Vishay, TI, etc.
There are two addressing options:
The CD4066 has multiple, independent switches, and any of them can be on/off in any combination because there is one enable input per switch with no internal decoding.  Three possible output states require three address lines.
The CD4052 has an address decoder and two sections, each with 4 switches.  The switches are mutually exclusive - only one can be on at a time (per 4:1 section).  Three output states require two address lines .
