Part Number: TS3A44159
I am using the TDC1000-7200 GASEVM for liquid ultrasonic sensing using 1MHz transducers and I need a 2:1 switch for impedance matching the Tx and Rx lines. I managed to use the TS3A44159 without the boost converter as it can handle 5V and it worked fine. Now I need to find a similar switch in terms of T_off/on time and channels that can handle up to 30V input signals that the boost converter provides.
I tried to ask in the ultrasonic sensing forum but I have not gotten any answer.
Do you have any suggestion of suitable switch from you or third party?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Fan.Wang:
Thank you for your answer. We need to have four channels as illustrated in the circuit below:
Also, 125ohm is a bit high as it will affect the impedance matching.
In reply to Thibault Helle:
Thanks for putting a diagram into our discussion. Unfortunately, Our 4-channel 2:1 multiplexer that supports 30V has not been released to market.
