描述 Description

SD 3.0-compliant memory card integrated dual voltage level translator with EMI filter and ESD protection - The device is an SD 3.0-compliant 6-bit bidirectional dual voltage level translator. It is designed to interface between a memory card operating at 1.8 V or 2.9 V signal levels and a host with a fixed nominal supply voltage of 1.7 V to 3.6 V. The device supports SD 3.0, SDR104, SDR50, DDR50, SDR25, SDR12 and SD 2.0 high-speed (50 MHz) and default-speed (25 MHz) modes. The device has an integrated voltage selectable low dropout regulator to supply the card-side I/Os, built-in EMI filters and robust ESD protections (IEC 61000-4-2, level 4).

特性 Features
