Switches expand SD, SDIO, MMC connection

The FSSD06 and FSSD07 2:1 multiplexer memory switches expand communication between SDIO, SD, and MMC peripherals and processors. The FSSD06 allows two peripherals to write/read to one processor, and the FSSD07 allows two processors to write/read to one peripheral.

The ICs operate from 1.65 to 3.6 V with built-in voltage translation and conform to Secure Digital, Secure Digital I/O, and Multimedia Card specifications. They come in 24-lead MLP (3.5 x 4.5-mm) or UMLP (2.5 x 3.4-mm) packages, require only 2 µA of supply current maximum, and provide 10-kV ESD protection. ($0.71 to $1.36 ea/1,000 — samples available now.)
