TMUX7234: TMUX7234PWR

Hello 

Today is a us ti holiday it please expect a response in this early next week

Hi Tirthal,

The TMUX7234 is likely the best option for your in this application and I would like to point out a couple things just so you can get a idea of how this device can perform in your application.

1.This device can support io signals ranging VDD-VSS or GND. So for example it can pass signals from 0V to 36V when VSS and GND=0V and VDD=36V.

Conversely for example it can handle +/-15V input signals when VDD=15V and VSS=-15V.

Will you be passing signals with negative voltage through the device as the device will need to be used in dual supply to do that?

2.This device is typically recommended for high voltage applications like CAN and here is a app note to understand this more

3.The TMUX7234 can likely support the 2 MBPS to 100MBPS data transfer in  a 100base T application. The important thing to remember here is this is because of the bandwidth of the multiplexer being 100MHz and the actual frequency of the signals that will be passed through the device each signal path are 31.25 MHz based  of my understanding and research.( Please correct me if I am wrong here)  ( This means you can see some signal attenuation of the higher harmonics of your ethernet signal at 100MBPS but this should be fine. 

In addition here are a list of our typical ethernet multiplexers but they do not support 36V

Here is another app note that explain relays vs multiplexers and should be helpful for us here.

Please let me know what you think about this info and we can look into this more
