Answer:
MAX4704 is a passive mux/demux made with analog switches exclusively (i.e. no buffer, no amplifier) : therefore the device can be used as a multiplexer or demultiplexer;
depending on where are the input sources.

When used as a multiplexer the COM pin is the output. This is pin 9 on the uMAX and pin 12 on the QFN package.
When used as a de-multiplexer the NO pins (NO0 to NO3) are the output, and the COM pin is the input.
This is true for all passive analog multiplexers/demultiplexers
