FXL4T245BQX - Low Voltage Dual Supply 4-Bit Signal Translator

With Configurable Voltage Supplies, Signal Levels and 3-STATE Outputs

The FXL4T245 is a configurable dual-voltage-supply translator designed for bi-directional voltage translation of signals between two voltage 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. Both ports are designed to accept supply voltage levels from 1.1V to 3.6V. This allows for bidirectional 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 VCCs reach active levels allowing either VCC to be powered-up first. The device also contains power down control circuits that place the device in 3-STATE if either VCC is removed.    PRODUCT TRAINING MODULE
