Product Introduction

Overview

The SN65HVD3082EDR is a half-duplex RS-485 transceiver produced by Texas Instruments. This device is designed to operate in RS-485 data bus networks and is fully compliant with the TIA/EIA-485A standard. It is powered by a 5-V supply and is optimized for signaling rates up to 200 kbps. The SN65HVD3082EDR is known for its low quiescent power consumption, making it ideal for power-sensitive applications. It features controlled transition times, which are suitable for transmitting data over long twisted-pair cables.

Key Specifications

Key Features

  • Meets or exceeds the requirements of the TIA/EIA-485A standard
  • Low quiescent power consumption (typically 0.3 mA in active mode and a few nanoamps in shutdown mode)
  • Industry-standard SN75176 footprint
  • Fail-safe receiver (bus open, bus shorted, bus idle)
  • Glitch-free power-up and power-down bus inputs and outputs
  • High ESD protection levels up to 15 kV
  • Wide common-mode range
  • Thermal-shutdown function to protect the device from damage due to system fault conditions
  • Power-on-reset circuits to keep the outputs in a high-impedance state until the supply voltage has stabilized

Applications

The SN65HVD3082EDR is suitable for various demanding applications, including:

  • Energy meter networks
  • Electrical inverters
  • Status and command signals across telecom racks
  • Cabled chassis interconnects
  • Industrial automation networks where noise tolerance is essential
