TMUX1574: I2C mux

Part Number: TMUX1574

Hi team,

Customer would like to use TMUX1574 as a mux for 2 slave device, do they need to get pull up resistor as both side of TMUX1574?

Thanks and Best Regards,

Will

  • In general, yes. To prevent floating I²C signal lines, you need pull-up resistors on all bus segments that can be disconnected from the others.

    (On bus segments without an I²C master, these pull-ups are not needed to support communication, and can be made weaker to save power.)
