TS3USB221A: FSUSB20MUX alternative

Hi Abigail,

For this mux, in terms of package, I think the TS3USB30E is the closest we have for MSOP package, and the TS3USB3000 is the closest thing we have for the MicroPak package. I don't believe we have anything for the DQFN package. Outside of packages requirements, our typical recommendation is the TS3USB221, yes.

Thanks,

Ryan

Thank you for the quick response! The customer let me know they are looking for a drop-in replacement that is mechanically compatible with the (FSUSB20MUX) part with no copper changes. So it sounds like the TS3USB30E or TS3USB3000 is maybe the closest based on the package, but still not drop in compatible options? 

Hi Abigail,

Do you know what package they're using? The datasheets I can find online (seems like the FS device is OBS) have 3 different packages, so if they're using using one of the same packages as the two muxes I sent, those may be drop-in options. As long as the pin layouts are the same, I imagine functionality will be the same too.

Thanks,

Ryan

They let me know the package is10-TFSOP, 10-MSOP (0.118", 3.00mm Width), labelled FSUSB20MUXTR-ND on digikey

Thank you Ryan!! This is super helpful, I will run it by the customer
