Description
FXL3SD206 is a voltage translator with multiplexing and
de-multiplexing functions for SDIO devices. 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 tracks the VDDA. Ports B and C are
intended to connect to peripheral devices. Peripheral
I/O voltage levels track either VDD_HI or VDD_LO as
determined by the VDD_SEL pin. During normal
operation, VDD_HI must be greater than or equal to
VDD_LO. The CH_SEL, VDD_SEL, and OE pins are
referenced to VDD_CON. Channel communication from
either Port A to Port B or Port A to Port C is controlled
by the CH_SEL pin.
The selected channel remains in 3-state until the VDD of
each side reaches an active level and the OE pin
reaches a valid high. Internal power-down circuitry
places the selected channel of the device in 3-state if
either side VDD removed.
The direction of data is controlled automatically by the
device. No direction control pin is required. The device
senses input signals on any port automatically and
transfers the data to the corresponding output.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device
reliability. The absolute maximum ratings are stress ratings only.

Recommended Operating Conditions(3)
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to Absolute Maximum Ratings.
