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.

Features

■ One-way (unidirectional) translation between any 2 levels from 1.1V to 3.6V

■ Fully configurable, inputs and outputs track respective VCC levels

■ Non-preferential power-up sequencing; either VCC may be powered-up first

■ Outputs remain in 3-STATE until active VCC level is reached

■ Outputs switch to 3-STATE if either VCC is at GND

■ Power-off protection

■ Control input (OE) level is referenced to VCCI voltage

■ Packaged in 14-terminal DQFN (2.5mm x 3.0mm) package

■ 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)
