**ADG3247BRUZ: A 5V to 5V, 2-Channel Level Translator with High-Speed 24Mbps Performance**

In modern electronic systems, the need to seamlessly interface between devices operating at different voltage levels is a common design challenge. While many level translators handle conversion between disparate voltages like 1.8V and 3.3V, a unique and critical requirement exists for **voltage-level translation between two 5V digital domains**. The **ADG3247BRUZ from Analog Devices** addresses this specific need, offering a robust and high-performance solution for **preventing harmful back-driving and ensuring signal integrity** across isolated 5V systems.

This 2-channel bi-directional translator is engineered to **pass digital signals between two 5V buses** that are sourced from different power supplies. This is crucial in complex systems where separate 5V rails might be used for analog and digital sections, or for hot-swappable boards, to avoid current flow between the supplies when one is powered down. The ADG3247BRUZ effectively creates a break in the path, allowing data to flow while isolating the power domains.

A standout feature of the ADG3247BRUZ is its **high-speed performance, supporting data rates up to 24Mbps**. This makes it suitable for a wide range of medium-speed interfaces, including **SPI, SDIO, UART, and GPIO** signal translation. Its fast switching speed ensures that data integrity is maintained without introducing significant propagation delays, which is vital for synchronous communications.

The device operates with two separate voltage supplies, VCCA and VCCB, both of which can be set to 5V. The architecture uses **N-channel MOSFET pass gates** in conjunction with special circuitry to detect the input signal level and control the switch state accordingly. This design provides a **low ON-resistance (Ron)** and minimizes static power consumption, enhancing efficiency.

Housed in a compact **16-lead TSSOP package**, the ADG3247BRUZ is designed for space-constrained applications. Its **bidirectional capability per channel** simplifies board layout by reducing the number of components required, as the direction of data flow is automatically determined by the input signals.

**ICGOOODFIND**

The ADG3247BRUZ is an indispensable component for designers working with multiple 5V power domains. It excels in providing **critical isolation, high-speed data translation at 24Mbps, and robust signal integrity**, all within a compact and easy-to-use bidirectional package. It is the ideal solution for ensuring reliable communication in industrial control, telecommunications, computing systems, and any application where voltage domain isolation at 5V is paramount.
