NVT4857UKZ Product Details

The device is an SD 3.0-compliant bidirectional dual voltage level translator withauto-direction control. It is designed to interface between a memory card operating at1.8 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 (50MHz) and Default-Speed (25 MHz) modes. The device has an integrated voltage selectablelow dropout regulator to supply the card-side I/Os, an auto-enable/ disable functionconnected to the VSD supply pin, built-in EMI filters and robust ESDprotections (IEC 61000-4-2, level 4).


  • Supports up to 208 MHz clock rate
  • SD 3.0 specification-compliant voltage translation to support SDR104, SDR50,DDR50, SDR25, SDR12, High-Speed and Default-Speed modes
  • 1.2 V to 1.8 V host side interface voltage support
  • Feedback channel for clock synchronization
  • 100 mA Low dropout voltage regulator to supply the card-side I/Os
  • Low power consumption by push-pull output stage with break-before-makearchitecture
  • Automatic enable and disable through VSD
  • Integrated pull-up and pull-down resistors: no external resistors required
  • Integrated EMI filters suppress higher harmonics of digital I/Os
  • Integrated 8 kV ESD protection according to IEC 61000-4-2, level 4 on cardside
  • Level shifting buffers keep ESD stress away from the host (zero-clampingconcept)
  • 20-ball WLCSP; pitch 0.4 mm
Target Applications
  • Smart phones
  • Mobile handsets
  • Digital cameras
  • Tablet PCs
  • Laptop computers
  • SD, MMC or microSD card readers
