ARINC 429 IC Line Drivers & ARINC 429 Avionics Serial Bus 

 
What is a line driver?

A Line Driver is an integrated circuit (IC) designed to drive a signal onto an ARINC 429 data bus.

Based on the ARINC 429 specification for serial communication, Device Engineering has developed a complete product line of Line Drivers that convert TTL or CMOS signals to differential RZ data on the ARINC 429 avionics serial bus. These devices will also interface similar RZ type buses including ARINC 571 and ARINC 575. Many of the line drivers also support differential NRZ type serial buses such as RS-422. Talk to an engineer today to learn more about our Line Drivers, including ARINC 429 Line Drivers and ARINC 429 Avionics Serial Bus.

Key functions include:

  • Signal Conversion – Translates digital signals into differential RZ formats for ARINC 429 communication.
  • Noise Immunity – Enhances signal integrity by minimizing electrical interference.
  • Voltage Level Shifting – Ensures compatibility between various system voltage levels.

Choosing ARINC 429 Line Drivers for Your Design

Selecting the right ARINC 429 line driver depends on key design factors such as power efficiency, signal integrity, and package type.

Device Engineering offers a range of packaging options to meet specific industry requirements:

  • CERDIP (Ceramic Dual Inline Package) – High-reliability environments with superior temperature resistance.
  • SOIC (Small Outline Integrated Circuit) – Compact, surface-mount design for space-constrained applications.
  • PLCC (Plastic Leaded Chip Carrier) – Ideal for socketing and surface mounting.
  • MLPQ (Metal Leadframe Quad Flat Pack) – Optimized for high-performance applications in small form factors.
  • CLCC (Ceramic Leadless Chip Carrier) – Robust ceramic construction with enhanced durability.
  • EP (Exposed Pad) – Improved thermal dissipation for high-power applications.

Applications of ARINC 429 Line Drivers

These line drivers are widely used across avionics systems, supporting critical functions that require secure and accurate data transmission.

Common applications include:

  • Flight Control Systems – Facilitates seamless communication between avionics subsystems.
  • Navigation Equipment – Ensures precise data exchange between GPS and onboard computers.
  • Aircraft Monitoring Systems – Enables real-time diagnostics and system performance analysis.
  • Data Bus Interfaces – Supports ARINC 571, ARINC 575, and other RZ-based communication buses.

ARINC 429 Protocol Overview

The ARINC 429 data bus is the industry standard for digital communication in commercial and military aircraft. It utilizes a differential signaling method to ensure data accuracy and minimize signal degradation over long distances. ARINC 429 operates in simplex mode, meaning data is transmitted in a single direction from one system to multiple receivers.

Key ARINC 429 Features:

 

  • High Noise Immunity – Reduces electromagnetic interference (EMI) using differential transmission.
  • Standardized Data Encoding – Uses return-to-zero (RZ) and non-return-to-zero (NRZ) encoding methods.
  • Error Checking – Includes parity bits to detect and correct transmission errors.
