The FSSD06 is a two-port multiplexer that enables Secure Digital (SD), Secure Digital I/O (SDIO), and Multimedia Card (MMC) master control to be extended to multiple cards or peripherals. This configuration allows CMD, CLK, and D[3:0] signals to be multiplexed to dual-card peripherals. It is suitable for 1-bit/4-bit SD/MMC applications. The architecture includes the necessary bi-directional data and command transfer functions for either a single high voltage card or a dual voltage power supply card. The clock path of the FSSD06 is a unidirectional buffer with an integrated pull-up for high-impedance mode. Typical applications are switches in mobile and consumer applications: cellular phones, digital cameras, home theater displays, mobile GPS devices, and printers.
