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?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
