The FXL2SD106BQX is a configurable dual-voltage-supply translator designed for both uni-directional and bidirectional 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 VCCA level and the B port tracks the VCCB level. This allows for bi-directional voltage translation over a variety of voltage levels: 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V.The device remains in 3-state until both VCC reach active levels, allowing either VCC 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 A and B ports by placing them in a 3-state condition. The FXL2SD106BQX is designed so that OE and CLK IN are supplied by VCCA. The device senses an input signal on A or B port automatically. The input signal is transferred to the other port. The FXL2SD106BQX is not designed for SD card applications. The internal bus hold circuitry conflicts with pull-up resistors. SD cards have internal pull-up resistors on the CD/DAT3 pins.
Feature
