Product Introduction

Overview

The ADM4854ARZ is a differential line transceiver designed by Analog Devices Inc. for high-speed, full-duplex data communication on multipoint bus transmission lines. This device is particularly suited for applications requiring reliable and efficient data transmission over long distances. It features dedicated differential line driver outputs and receiver inputs, enabling it to support up to 256 transceivers on a single bus. The transceiver is compliant with EIA RS-485 and RS-422 standards, making it versatile for various communication protocols.

Key Features

  • True fail-safe receiver inputs ensuring a logic high output level when inputs are open or shorted.
  • Reduced slew rates for low electromagnetic interference (EMI).
  • Outputs are high-Z when disabled or powered off to avoid bus overloading.
  • Thermal shutdown and short-circuit protection for enhanced reliability.
  • Low power consumption with a maximum supply current of 5 µA in shutdown mode.
  • Supports up to 256 transceivers on one bus due to 1/8-unit load receiver input impedance.

Applications

  • Low power RS-485 applications.
  • EMI sensitive systems.
  • DTE to DCE interfaces.
  • Industrial control systems.
  • Packet switching and local area networks.
  • Level translators.
