    It does not make sense to call a 1:1 (SPST) a multiplexer.

    For N:1 (with N > 1) devices, it does not matter whether you call them switches or multiplexers.

    Hello Anna,

    The TMUX7612 is called an analog switch because it has a 4-channel 1:1 configuration, which is basically means 4 separate channels each one having a single switch. 

    TMUX8108 is called a multiplexer because of its 8:1 configuration. Having 8 inputs going into one output, or vise versa selected by the logic pins. 

    As Clemens said, it doesn't really matter.

    Thanks,

    Nir
