General Description

The device is an SD 3.0-compliant bidirectional dual voltage level translator with auto-direction control.

It is designed to interface between a memory card operating at 1.8 V or 3.0 V signal levels and a host with a nominal supply voltage of 1.2 V to 1.8 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.

Overview

NVT4857UK SD 3.0-SDR104 compliant integrated auto-direction control memory card voltage level translator with EMI filter and ESD protection Rev.
