Applications
The SN65HVD3082ED is widely used in industrial automation and building control systems where multi-drop RS-485 networks connect PLCs, sensors, and actuators over long cable runs. It suits HVAC controllers, motor drives, and smart metering applications that demand reliable half-duplex data communication at up to 10 Mbps. Its high node count and ESD robustness also make it a preferred choice for RS-485 fieldbus installations in factory and process automation environments.

Frequently Asked Questions
What is the maximum data rate supported by the SN65HVD3082ED?
The SN65HVD3082ED supports data rates up to 10 Mbps, making it suitable for high-speed RS-485 networks. At longer cable distances the practical rate is lower; for a 1200 m bus, 100 kbps is a typical operating point to maintain signal integrity.
How many nodes can be connected on a single RS-485 bus using SN65HVD3082ED?
Because the SN65HVD3082ED presents only 1/8-unit load on the bus, a single RS-485 network can accommodate up to 256 devices (nodes) when all transceivers have this 1/8-unit load specification, compared to just 32 nodes with standard 1-unit-load devices.
What ESD protection does the SN65HVD3082ED offer on its bus pins?
The bus pins (A and B) of the SN65HVD3082ED are protected to ±15 kV using the Human Body Model (HBM), providing robust protection against electrostatic discharge events common in industrial field wiring and hot-plug scenarios.
What package is the SN65HVD3082ED available in, and what are its dimensions?
The SN65HVD3082ED comes in an 8-pin Small Outline IC (SOIC) package (JEDEC R-PDSO-G8), which measures approximately 4.9 mm × 3.9 mm. This compact SMD footprint is compatible with standard PCB reflow assembly processes.
Can the SN65HVD3082ED replace the SN75HVD3082E?
Yes. The SN65HVD3082ED is the industrial-grade version (−40°C to +85°C) while the SN75HVD3082E covers the commercial temperature range (0°C to +70°C). They are pin-compatible and functionally identical, so the SN65HVD3082ED is a direct drop-in upgrade for wider temperature operation.
