Description
The DIO74506 is an SD 3.0-compliant bidirectional
dual-supply level translator featuring auto direction
control. It is designed to interface between a memory
card operating at 1.7 V to 3.6 V signal levels and a
host with a typical supply voltage of 1.1 V to 1.95 V.
The device supports SDR104, SDR50, DDR50,
SDR25, SDR12 and SD2.0 high-speed (50 MHz) and
default-speed (25 MHz) modes.
