Does any Data MUX(SPDT) integrated level shift(1.8V to 3.3V) that it is also support bandwidth of SDIO 3.0?

Mickey,

I believe we have some switches that have integrated level shift feature at TI. I believe assistance for these types of devices is located in the logic forum. I will move this thread to the logic forum so they may assist you.

Thank you,

Adam

Hi Mickey,

We don't have a 1:2 mux that also does level shifting, but I do have parts that do level shifting, and 1:2 muxes separately. How many channels of data do you want to translate/switch and at what maximum frequency?

Hi
We need to 8 channels for data switching and speed up to 25MHz.

Hi Mickey,

i dont know of any low to high translating switch but we do have high to low switches.

I would recommend looking into a pair of LSF0108's for the data translation (8 bit passive translator) configured as shown below. I already had a diagram with the 2 bit version of the device, but the 8 bit is essentially the same.
