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 V_CCI level, and Y Outputs track the V_CCO 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 V_CCs reach active levels allowing either V_CC to be powered-up first. The device also contains power down control circuits that place the device in 3-STATE if either V_CC is removed. The OE# input, when HIGH, disables the outputs by placing them in 3-STATE condition.

• One-way (unidirectional) translation between any 2 levels from 1.1V to 3.6V
• Fully configurable, inputs and outputs track respective V_CC levels
• Non-preferential power-up sequencing; either V_CC may be powered-up first
• Outputs remain in 3-STATE until active V_CC level is reached
• Outputs switch to 3-STATE if either V_CC is at GND
• Power-off protection
• Control input (OE#) level is referenced to V_CCI voltage
• Packaged in 14-terminal DQFN (2.5mm x 3.0mm) package
• ESD protection exceeds:
