TS5A22364: audio input signal routing

Hello to the community

i was wondering if placing an sr latch before in1 and in2  it could be possible to give to audio source1 the nc1-no2, and to audio source2 the no1-nc2 path.

the reason of this is just to have a single switch with led associated for both sources.

to my knowledge should be ok and but i can't find nothing about the internal circuitry, plus there's no trace on the web of THAT kind of design so i've thought there's just one possibility over 1 billion that i may be wrong :-)

you can check it  easyeda.com/.../ti-switch

thank you

  • Hi Alessandro,

    Using an SR Latch at the IN pins should not be an issue, but make sure that the V_OH(latch) > V_IH(mux) and V_OL(latch) < V_IL(mux). Also make sure that there is always a defined logic level on the IN pins, or else the audio could be pulled from source 1 and source 2. Besides that I see no issue with this application. 

    Best Regards,

    Parker Dodson

    i'm going to use the sn74lvc2g02, 5Vcc, i've checked and it should fit.

    thank you for your kind reply
