ISO3082DW – 5V 20Mbps Half-Duplex RS-485 Transceiver with 2.5kVrms Isolation (SOIC-16)

Description

The ISO3082DW is a high-speed, isolated RS-485 transceiver that provides robust protection for differential data communication. By integrating a 2.5kVrms galvanic isolation barrier, this device effectively separates the logic side from the bus side, protecting sensitive controllers from high-voltage transients, noise, and ground potential differences that are common in industrial and long-distance networking.

Engineered for performance, the ISO3082DW supports data rates of up to 20 Mbps, making it suitable for high-speed industrial fieldbus communication. It operates in half-duplex mode and is designed to maintain signal integrity over long cables in electrically harsh environments. With its integrated isolation technology, this transceiver eliminates the need for external optocouplers, significantly reducing board space and simplifying the design of reliable serial interfaces.

Housed in a compact SOIC-16 (SMD) package, it is ideal for high-density PCB designs in automation, renewable energy systems, and telecommunications equipment where safety and reliable communication are paramount.
