Description
The TPT24857 is an SD 3.0 spec-pliant memory card voltage-level translator with bidirectional control. It is designed to translate voltage between voltage 1.8 V to 3.0 V in card side and 1.2 V to 1.8 V in host side.
The device supports SD 3.0 SDR104 in high speed mode, and covers down to SDR50, DDR50, SDR25, SDR12 & SD 2.0 (50 MHz and 25 MHz) modes. The TPT24857 has an integrated...
