ESD Protection, High-Speed Data Communication Capable
Can Be Used Across Wide Temperature Ranges

Analog Devices (ADI) has launched two new 50 Mbps-class RS-485/RS-422 transceivers that can be used in harsh environments such as industrial automation, motor control, defense, and aerospace electronics.

The ADM3065E and ADM3066E transceivers provide IEC6100-4-2 Level 4 ESD protection, high-speed data communication, and 1.8 VIO logic supply (ADM3066E) in a compact, space-saving package and can be used across a wide range of industrial temperature ranges. These features enable flexible design, simplify implementation, and enhance the performance of standard RS-485 communication links.

System-level IEC ESD threats have higher peak discharge current and voltage compared to HBM (Human Body Model) ESD. The IEC ESD rating protection function of ADM306xE provides a robust solution for customers who want to operate in industrial environments. The ADM306xE transceiver series has receiver fail-safe applied, which can prevent fault issues such as wiring errors that occur in real-world environments and cause open or short circuits. The receiver fail-safe function maintains the existing state on the data bus.

Glitch-free hot-swap capability enables error-free data operations when circuit boards are inserted into a backplane for proper motor control, accurate instrument reading, and smooth machine operation based on valid data. Additionally, the RS-485 transceiver complies with widely used protocols such as Profibus, BACnet, and Modbus, and supports various network topologies.


The operating voltage range of the ADM306xE transceiver series is 3~5.5V at VCC. The ADM3066E integrates VIO logic supply, enabling variable digital interface operation even at a minimum of 1.62V, and can be directly connected to low-power processors and FPGAs operating at 1.8V. The entire ADM306xE transceiver series provides, in addition to IEC61000-4-2 ESD protection provided on bus pins, receiver short-circuit, open-circuit, and floating input fail-safe protection functions.
