TMUX136: MUX Recommendation for UART application

Part Number: TMUX136

Hi,

My customer is looking for a mux that can meet the following requirements.  Could you help me with a recommendation?

Customer requirements:

3.3V on both sides and <10Mbit BW.

I’m looking for a 2:1 mux that I can use to switch the driver input on an RS422 Transceiver between a GPIO and a UART_TX line.

GPIO ->
                                    (MUX)    RS-422 Transceiver Driver
UART_TX -> 

I would also like a 1:2 De-mux so I can take the received signal and switch it between the UART_RX on the processor and another GPIO.

GPIO <-
                                    (MUX)    RS-422 receiver
UART_TX  <- 

Thanks,
Chuchen
