Low Voltage Dual Supply 5-Bit Signal Translator with Configurable Voltage Supplies and Signal Levels and 3-STATE Outputs

The FXL5T244 is a configurable dual-voltage-supply translator designed for one-way (unidirectional) 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. A Inputs and the OE# Control Pin track the VCCI level, and Y Outputs track the VCCO level. Both inputs and outputs are designed to accept supply voltage levels from 1.1V to 3.6V. This allows for unidirectional 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. The OE# input, when HIGH, disables the outputs by placing them in 3-STATE condition.
