    Sherry,

    From what I can tell CVBS is an AC signal with a voltage the goes below ground.  Some people have reported CVBS voltage as -1 V to 1 V or -0.3 V to 0.9V.  The TS5A22362 or some of the TMUX11xx family can support the negative voltage

    I typed in CVBS into the switches and multiplexers e2e search bar and found these posts. You can see one post where a customer was successful using the TS5A3357 and one was unsuccessful using the SN74LVC1G3157.   

    Thank you,

    Adam
