Dear team,

Customer want to use TMUX136 in 1.8V I2C application.

Can we use 3.3V power level on VCC and connect 1.8V I2C signal at mux in/out pins?

Thanks.

Regards,

Ben

    HI Ben,

    The TMUX136 will support 1.8V I2C signal through the mux in/out pins i.e. channels at VCC = 3.3V. This is valid operation. Please make sure the correct Pull-up resistors are on the bus on both the side of the switch to ensure I2C timing specifications.

    Thank you,

    Regards,
