FSSD06 Datasheet (Fairchild Semiconductor) - SD/SDIO and MMC Two-Port Multiplexer

FSSD06, SD/SDIO and MMC Two-Port Multiplexer

The FSSD06 is a two-port multiplexer that allows Secure Digital (SD), Secure Digital I/O (SDIO), and Multimedia Card (MMC) host controllers to be expanded out to multiple cards or peripherals.

This configuration enables the CMD, CLK, and D[3:0] signals to be multiplexed to dual-card peripherals.
