Hi Gopala,

It seems that a simple MUX like TMUX1248 would be fine for this solution. The main consideration here is that it does not interfere with the pull-down nature of the nINT line when active, and it remains high impedance while disconnected so any other SPI communication is not disrupted.

Let me know if you would like a different recommendation and I can connect you with our MUX's team which will have more insight on this particular recommendation.

Let me know if you have any more questions.

Regards,
Eric Schott

Hello Gopala,

The SN74LVC1G3157-Q1 is an automotive device that can fulfill the requirements of this system. It is similar to the tmux1248 but it is auto qualified.
