TMUX4052-Q1: Find URAT MUX

I don't need switch,I need MUX that two channels output at once

How should the two input signals be combined into one output signal?

Thanks for your recommendation, I think maybe some misunderstanding between us, all the switch we found now just can do switch function, that means input Uart signal can be transfer to output UartA/UartB, but not both UartA&UartB at one time. while we need an IC can split one UART to two UARTs simultaneously, the input UART signal can transfer to the two output UARTs at the same time, So could you help with this case ?

Creating two outputs from one input can be done with any two-channel buffer (e.g., SN74LVC2G17/34).

But what should happen when both devices at the right are transmitting at the same time? If you say that this does not happen, then you can use an AND gate (e.g., SN74LVC1G08) to combine the signals.

Hello Zhang,

I understand what you are asking for and based on Clemens suggestion I will move this forum to the logic team to confirm the solution Clemens offered.

TS3USB221A-Q1 is USB2 mux, but work for UART as well.
