It is designed for voltage translation over a wide range of input and output levels, from 1.65V to 3.6V. The multiplexing/de-multiplexing function of this device allows expansion of a host SDIO interface to two SDIO peripheral devices. When selected, each SDIO peripheral can communicate with the host through the same host interface. An alternative application allows two host devices to interface with a single SDIO peripheral. Port A is intended to connect to a host device and the voltage level ...
