Part Number: CD74HC4067
We need a MUX to fulfill UART 1:12 MUX function. Do you think we can use two CD74HC4067 chips (one for UART TX and one for UART RX) to make it? Please let me know if there's a better option.
If you're UART signal voltage and bandwidth is within the recommended operating conditions and your system can handle ~60 ohm series resistance the CD74HC4067 can work.
Most switches can support UART signals because of their low speeds and we even new ones like the TMUX136 (2-channel, 2:1 mux). Unfortunately, our portfolio doesn't have many options for 12:1 mux.
What you're you trying to communicate with that uses so many UART signals?

Thanks. It's used in server.
