TXS0206: Level shifter for SDIO

Franz-Josef Schuster

Part Number: TXS0206

Hello team,

I need a level shifter for my SDIO-Interface (SDR25 or faster). The master must be powered at 3.3V. The slave can only be powered at 1.8V. Which level shifter would you recommend?

AEC-Q is not required. 85°C should be enough. Are there any alternatives with a higher temperature?

Regards,

Franz-Josef

Hi Franz,

SDR25 generally has CLK with max frequency of 50MHz, which is supported by the TXS0206A for this application. The TXS0206-29 can also be realized if -40C to 125C operation is desired.

Regards,

Jack

According to the data sheet, the TXS0206-29 is also only specified for temperatures up to 85°C. Only the LDO specifies a junction temperature of 150°C.
Are there any other level shifters designed for a higher frequency?

Hi Franz,

Thanks for clarifying my typo- unfortunately the TXS0206A is the best fit for SDR25, there isn't any support for SDR50 or higher speeds as of today.

Regards,

Jack
