Hi Expert,

If TS5A223 Vcc=0, SELx=0, does NC1=COM1 and NC2=COM2? Or other analog switch can support it. (headphone signal.) Thanks!

    Jerry,

    Are you asking if the signal path will conduct with there is no power to Vcc?  This type of device will be called a depletion FET and we do not have any of these devices at this time as see in the FAQ below.

    If you would like a switch that will support audio signals please look at the TS5A22362, TS5A22364, TS5A22366.

    Thank you,

    Adam
