TXS02612 when not using SDIO

Other Parts Discussed in Thread: TXS02612

I am designing with TXS02612. I am not using an SDIO peripheral, can I leave all the DATxx1 signals as NC (No Connect)? Should I ground the SEL pin so the MUX is always set to the SD/MMC memory card?

    Michelle,

    For your application, you can leave the DATxx1 pins floating (they will be terminated to VCCB1 via an internal 70kohm pullup resistor) and ground the SEL pin since the SDIO peripheral path is never needed.
