ON Semiconductor FXLA0104QFX Bidirectional Voltage Level Translator

The FXLA0104QFX from ON Semiconductor is a highly versatile, bidirectional voltage level translator designed for multi-voltage digital system applications. This compact device is engineered to provide a reliable interface between low-voltage digital circuits and higher voltage digital circuits without the need for an external direction control signal. Its main purpose is to ensure smooth communication and compatibility between devices operating at different voltage levels, which is a common requirement in modern electronic systems.

The FXLA0104QFX features four bidirectional channels, making it suitable for translating four signal lines. Each channel is equipped with ON Semiconductor's advanced auto-direction sensing technology, which eliminates the need for a direction control pin and simplifies circuit design. This technology ensures that the FXLA0104QFX automatically detects the direction of data flow and adjusts accordingly, providing a seamless translation between different voltage domains.

With a wide operating voltage range of 1.1V to 3.6V on the A side and 1.65V to 5.5V on the B side, the FXLA0104QFX is capable of interfacing between a broad range of digital logic levels. This makes it an ideal choice for applications that involve interfacing low-voltage microcontrollers with peripherals that operate at higher voltages, such as sensors, ADCs, or communication interfaces.

The device also boasts a high-speed performance with a guaranteed data rate of up to 100 Mbps, making it suitable for high-speed signal translation in fast communication protocols. Additionally, the FXLA0104QFX features a power-off protection circuit that ensures the high-side outputs remain in a high-impedance state when the device is powered down, preventing potential damage to connected components.

Encased in a small UQFN-10 package, the FXLA0104QFX is designed to occupy minimal space on a PCB, making it an excellent choice for space-constrained applications. Its robust design includes ESD protection on all pins, providing enhanced reliability and longevity in harsh electrical environments.

In summary, the ON Semiconductor FXLA0104QFX is a high-performance, auto-sensing, bidirectional voltage level translator that is essential for modern multi-voltage digital systems, offering ease of use, flexibility, and protection in a compact form factor.
