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.
