TMUX1119: does TMUX1119DCKR works with open-drain Pins?

Hello,

I would like to know, if TMUX1119DCKR works with open-drain Pins? For example, for the application to cut the device out of a I2C Bus

Thanks!

    Lin Lu,

    The TMUX devices like all the passive FET switches can work with open-drain and push-pull drivers.  These parts simply pass the voltage from the drain to the source and can work with any source and load as long as the signal voltage and currents are within the recommended operating conditions.  

    The TMUX11xx devices are part of our precision family with extremely low on-state leakage current and are overkill for simple I2C switches.  

    You can use the Ti.com switch selection tool to filter for the feature supports I2C to find better options like the TMUX1072 or TMUX154E.    

    Thank you,
