The FXL2SD106 is a configurable dual voltage supply converter for unidirectional and bidirectional voltage translation between two logic levels. The device enables voltage translation between as high as 3.6V and as low as 1.1V. The A port tracks the VCCA level and the B port tracks the VCCB level. Bidirectional voltage translation between multiple voltage levels: 1.2V, 1.5V, 1.8V, 2.5V and 3.3V. The device will remain 3-stated until both VCCs reach active levels, allowing either VCC to power up first. If either VCC is removed, an internal power-down control circuit places the device in 3-state. When the OE input is low, it places both the A port and the B port in a high-impedance state, thereby disabling both. The FXL2SD106 is designed so that OE and CLK IN are powered by VCCA. The device automatically senses the input signal on either the A port or the B port. The input signal is routed to another port. The FXL2SD106 is not suitable for SD card applications. Internal bus-hold circuitry conflicts with pull-up resistors. SD cards have an internal pull-up resistor on the CD/DAT3 pin.
