Features

Bi-directional interface between two levels from 1.1V to 3.6V Fully configurable: Inputs and outputs track V CC level Non-preferential power-up; either VCC may be powered-up first Outputs remain in 3-state until active V CC level is reached Outputs switch to 3-state if either V CC is at GND. Power off protection Bushold on data inputs eliminates the need for SDIO pull-up resistors Control input (OE and CLK IN) are referenced to V CCA voltage Packaged in 16-terminal DQFN (2.5mm x 3.5mm) Direction control not needed 80 Mbps throughput when translating between 1.8V and 2.5V ESD protection exceeds: – 12kV HBM (B port I/O to GND) (per JESD22-A114 & Mil Std 883e 3015.7) – 8kV HBM (A port I/O to GND) (per JESD22-A114 & Mil Std 883e 3015.7) – 1kV CDM (per ESD STM 5.3) General Description The FXL2SD106 is a configurable dual-voltage-supply translator designed for both uni-directional and bi- directional voltage translation between two logic levels. The device allows translation between voltages as high as 3.6V to as low as 1.1V. The A port tracks the V CCA level, and the B port tracks the V CCB level. This allows for bi-directional voltage translation over a variety of volt- The FXL2SD106 is specifically designed as a translator to interface with the SDIO standard. I/O capacitance is managed to meet the SD maximum capacitance specifi- cation. The B side ESD performance allows interface as an external card and the part can handle 80 Mbps throughput when translating between 1.8V and 2.5V. The device remains in 3-state until both V CC s reach active levels allowing either V CC to be powered-up first. Internal power down control circuits place the device in 3-state if either VCC is removed. The OE input, when low, disables both the A and B ports by placing them in a 3-state condition. The FXL2SD106 is designed so that both control pins (OE and CLK IN) are supplied by V CCA The device senses an input signal on A or B port automatically. The input signal is transferred to the other port.

This benefit derives from the chip design. When either V CC is at 0 volts, outputs are in a high-impedance state. The control input (OE) is designed to track the VccA supply. A pull-down resistor tying OE to GND should be used to ensure that bus con- tention, excessive currents, or oscillations do not occur during power-up/power-down. The size of the pull-down resistor is based upon the current-sinking capability of the device driving the OE pin. The recommended power-up sequence is the following: 1. Apply power to the first V CC 2. Apply power to the second V CC 3. Drive the OE input high to enable the device. The recommended power-down sequence is the following: 1. Drive OE input low to disable the device. 2. Remove power from either V CC 3. Remove power from other V CC Number Name Description CCA A Side Power Supply

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. Note: 1. I O Absolute Maximum Rating must be observed. Recommended Operating Conditions (2) 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. Note: 2. All unused inputs and I/O pins must be held at V CCI or GND.
