Hi, everyone, please help me solve a problem: Is there a switch IC with multiple CVBS signal inputs and single CVBS signal output? It is a multi-input single-output multiple-select IC. I need 5 inputs and 1 output, 6 inputs and 1 output, 7 inputs and 1 output. Please recommend a master

Relay

Or a multiple-choice analog switch, but one bad thing about the analog switch is that all the pins cannot be left floating. It took a lot of effort to debug it.

Is it only the relay that can be operated in this way? Is there any chip that can be directly hacked?

It's really troublesome,, I really don't know what to do. Thank you, brother

MC14051BCP 8-to-1 analog switch/data selector CMOS logic IC, take a look at the datasheet of this chip to see if it meets your requirements

Which relay can do this? Maybe you can try it.

It depends on what kind of relay you need. How would I know which relay you choose? You are making things difficult for me.

Didn't I give you an eight-choice analog switch? See if it meets your requirements.

You can use a high-bandwidth analog switch and go to the official website of TI, MAXIM, etc. to select the model according to your needs.
