FXL5T244 Low Voltage Dual Supply 5-Bit Signal Translator with Configurable Voltage Supplies and Signal Levels and 3-STATE Outputs
General Description
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.

Features
s One-way (unidirectional) translation between any 2 levels from 1.1V to 3.6V s Fully configurable, inputs and outputs track respective VCC levels s Non-preferential power-up sequencing; either VCC may be powered-up first s Outputs remain in 3-STATE until active VCC level is reached s Outputs switch to 3-STATE if either VCC is at GND s Power-off protection s Control input (OE) level is referenced to VCCI voltage s Packaged in 14-terminal DQFN (2.5mm x 3.0mm) package s ESD protection exceeds: 4kV HBM ESD (per JESD22-A114 Mil Std 883e 3015.7) 8kV HBM I/O to GND ESD (per JESD22-A114 Mil Std 883e 3015.7) 1kV CDM ESD (per ESD STM 5.3) 200V MM ESD (per JESD22-A115 ESD STM5.2)
