70V Fault-Protected RS-485 Transceiver IC for Industrial Communication with Wide Common-Mode Range (SOIC-8)

The SN65HVD1781DR is a robust RS-485 transceiver IC designed for reliable differential data communication in harsh industrial environments. It integrates a differential driver and receiver operating from a single supply, enabling seamless half-duplex communication over long cable distances. With support for multipoint bus systems and wide common-mode voltage tolerance, this device ensures stable communication even in electrically noisy conditions such as factory automation and field networks.

Engineered with advanced fault protection, the IC can withstand up to +-70V faults caused by wiring errors, short circuits, or cable damage, significantly improving system durability. High ESD protection further enhances reliability against electrostatic discharge events. The device is pin-compatible with industry-standard transceivers, allowing easy upgrades in existing designs. Its wide operating temperature range and compact SOIC-8 package make it ideal for industrial control, building automation, and rugged embedded communication systems.

Key Features

  • 70V Fault Protection: Survives overvoltage faults from miswiring, shorts, and cable damage
  • Integrated RS-485 Transceiver: Combines differential driver and receiver in a single IC
  • Wide Common-Mode Range: Ensures reliable communication in noisy industrial environments
  • Half-Duplex Communication: Suitable for two-wire RS-485 bus networks
  • High ESD Protection: Robust against electrostatic discharge events (HBM)
  • Drop-In Compatibility: Pin-compatible with SN75176 for easy replacement
  • Wide Temperature Range: Operates from −40 C to+125 C
  • Low Power Operation: Optimised for efficient industrial and embedded systems
  • Compact Package: SOIC-8 for space-efficient PCB design
