Hi Shu-Cheng,
We do not have any reference schematic or app note specifically for this device.
The functional diagram given in the datasheet could be used as a reference.

Hi Sirs,

Thanks for your reply.

Actually our source SD card don't have I2C, only have RST/CLK/DAT/PWR for signal, could we still use TXS02326A?

If Yes, may i know how to switch SIM card?

If no, have another solution can share? TS3A44159 or??

Thanks!!

Hi Shu-Cheng,

The Ts3A44159 is only an analog switch and doesnt provide any translation or drive.

The TXS02326A has 2:1 switch as well as dual supplies for voltage translation of the SIM card signals.

You could consider using TXS4558 as a dual SIM card level translation solution.
