Overview
The FXL4TD245UMX is a configurable 4-bit dual-voltage supply translator designed by onsemi. This device is capable of performing both uni-directional and bi-directional voltage translation between two logic levels, allowing translation between voltages as high as 3.6V and as low as 1.1V. The A Port tracks the VCCA level, and the B Port tracks the VCCB level, enabling bi-directional voltage translation over various voltage levels such as 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. The device features 3-STATE outputs and independent direction controls, ensuring that the outputs remain in 3-STATE until both VCC levels are active, and switch to 3-STATE if either VCC is at GND. This makes it suitable for a wide range of applications requiring flexible voltage translation.

Applications
The FXL4TD245UMX is designed for general usage and is suitable for many different applications that require flexible voltage translation. It is particularly useful in systems where different voltage domains need to communicate, such as in mixed-voltage systems, interface circuits, and in applications requiring level shifting between different logic levels.
