Part Number: TMUX6119
Other Parts Discussed in Thread: SN74LVC1G3157, TMUX154E

Hi Team,

I looking for a part like SN74LVC1G3157 but with EN pin, I found TMUX6119.

Can you advise if TMUX6119 is also for SDA and SCL signals?

Thanks,

Shlomi

    Shlomi,

    I think you are looking for a 2:1 switch to have 2x I2C devices talk to 1x I2C device.  You will also need a switch that has 2 channels one for SDA and one for SCL. 

    You are looking one with an enable pin so that you can have the option for the entire signal path to be Hi-Z impedance. 

      

    On ti.com switch search tool you can filter for configuration = 2:1, channel count = 2, and feature = supports I2C.  Or you can use the quick filter tool for Supports I2C.  There isn't a way to search if there is an enable pin but the first 3 listed do have EN pins.  It looks like the TMUX154E is lowest cost of the three.
