NVT4858
description
The device is an SD 3.0-pliant bidirectional dual voltage level translator with auto-direction control. It is designed to interface between a memory or SIM card operating between 1.62 V to 3.6 V signal levels and a host with a supply voltage of 1.08 V to 1.98 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 auto-enable/ disable function connected to the VCCB supply pin, built-in EMI filters and robust ESD protections (IEC 61000-4-2, level 4) on VCCB or any of the card side pins. External ESD diodes are not required.
This device also supports SIM card voltage level translator using CLK and two of the data lines for SD and SIM card bo sockets.
