70V Fault-Protected RS-485 Transceiver IC for Robust Half-Duplex Industrial Communication (SOIC-8)

The SN65HVD1785DR is a rugged RS-485 transceiver IC designed for reliable differential communication in harsh industrial environments. It integrates both a differential driver and receiver, enabling efficient half-duplex communication over a two-wire bus. With its wide common-mode voltage range, the device ensures stable data transmission across long cable distances and in electrically noisy conditions, making it ideal for industrial automation and distributed control systems.

Engineered for high reliability, the IC features +-70V fault protection to withstand miswiring, short circuits, cable damage, and other electrical faults. It also offers strong ESD protection, enhancing durability in real-world deployments. The device operates from a single supply and is optimised for multipoint RS-485 networks, while its compact SOIC-8 package allows easy integration into space-constrained PCB designs.

Key Features

  • +-70V Fault Protection: Survives shorts to power supplies and wiring faults
  • Half-Duplex RS-485 Communication: Suitable for two-wire bus systems
  • Wide Common-Mode Range: Reliable operation over long cables and noisy environments
  • Integrated Driver and Receiver: Simplifies RS-485 interface design
  • High ESD Protection: Robust against electrostatic discharge events (HBM)
  • Multipoint Communication Support: Ideal for industrial network topologies
  • Single Supply Operation: Simplifies power design
  • Industrial Temperature Range: −40 C to+105 C
  • Compact Package: SOIC-8 for efficient PCB layout
