FXL4T245 Low Voltage Dual Supply 4-Bit Signal Translator with Configurable Voltage Supplies and Signal Levels and 3-STATE Outputs April 2004 Revised June 2004 FXL4T245 Low Voltage Dual Supply 4-Bit Signal Translator with Configurable Voltage Supplies and Signal Levels and 3-STATE Outputs General Description Features The FXL4T245 is a configurable dual-voltage-supply trans-Bi-directional interface between any 2 levels from 1.1V lator designed for bi-directional voltage translation of sig- to 3.6V nals between two voltage levels. The device allowsFully configurable, inputs track V level CC translation between voltages as high as 3.6V to as low as Non-preferential power-up sequencing; either V may CC 1.1V. The A Port tracks the V level, and the B Port CCA be powered-up first tracks the V level. Both ports are designed to accept CCB No power-up sequencing required supply voltage levels from 1.1V to 3.6V. This allows for bi- Outputs remain in 3-STATE until active V level is directional voltage translation over a variety of voltage lev- CC els: 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. reached The device remains in 3-STATE until both V s reachOutputs switch to 3-STATE if either V is at GND CC CC active levels allowing either V to be powered-up first.
