Hi,

I would like to ask you a question about SN74CBTS16212.

Is it possible to use this device as analog switch like TS5A31xx/231xx, etc?

Thank you in advance.

Takumi,

It is possible to use this switch for some analog signals, however it is not recommended because it is not a bilateral switch. Since only n channel FETs are used to pass signals through this device, r_on will change drastically dependent on the voltage level being passed, and thus a large amount of distortion is likely to occur.

Please take a look at 'Selecting the Right Texas Instruments Signal Switch.' Although this is an older document, it is still very informative and applies to this situation.

Hi Emrys-san,

Thank you very much for your reply!

I understood well.

Though I tried to look at the link page you told me, I could not open due to the page seemed not to exist...

Sorry to ask you, could you tell me the link again?

Best Regards,

Takumi-san,

I have found that the link is correct, but for some reason it does not work from this page. Can you use Google to search for SZZA030 ? It should take you directly to the right document. Sorry for the extra trouble!
