Other Parts Discussed in Thread: SN74LV4051A

Tool/software:

Dear Staff,

I have to design a 8 channel to 1 Channel UART scanner and I'm focusing on TMUX1308A.

Mainly the PCB will contains the attached configuration.

My requs are:

3V3 power supply
all uarts are also at 3v3

Scope: I dont need to have all uart available at same time but I need them being accessed sequentially.

Could you please validate the architecture ?

Thanks a lot

Nicola

This will work.

Also consider the cheaper SN74LV4051A.

Hi Clemens,

thanks for supporting me.

Is there something similar chip to switch also USB2.0 ? Important is that al D+ and D- ara really close in order to have the controlled impedence intact with no loss.

Thanks

Not for 8:1; see ti.com/switches-multiplexers/protocol-specific/products.html#1389=USB 2.0 and ti.com/switches-multiplexers/analog/products.html#480=2&1611=3000;6500.
