SN74LV4052A bidirection and I2S usage

Other Parts Discussed in Thread: SN74LV4052A

Hi,

1)     I understand that SN74LV4052A is a mux and demux. Can we use it in two way direction? the explanation and application are as below:

1st case, when A is L

1Y2 send signal to 1-COM

2Y2 send signal to 2-COM

 

2nd case, when A is H

1-COM send signal to 1Y3

2-COM send signal to 2Y3

Could you advise if it's workable?

2)  Can we use SN74LV4052APWRG4 for I2S (audio) line? Is there any concern point?

Thanks

    This is an analog (de)mux, so an enabled connection between *Y* and COM* behaves like a small resistor; it cares neither about the voltage (as long as it's between the limits) nor about the direction of the current.

    It is possible to use it for I²S. Again, to determine the required drive strength of your signal sources, you can treat the (de)mux like a 75 Ω resistor.
