ARINC 429 Line Receivers
The ARINC 429 Line Receiver converts ARINC 429 differential RZ data to TTL/CMOS compatible outputs. Each lightning protected receiver channel operates independently and meets all requirements of the ARINC 429 Digital Information Transfer Standard. Please refer to the selection table below for Data Sheets on our ARINC 429 Line Receivers and Receiver Interface products.
What Is an ARINC 429 Line Receiver?
An ARINC 429 line receiver is a dedicated interface device that translates differential RZ signals from an ARINC 429 bus into standard TTL or CMOS digital logic levels. This conversion allows data from avionics subsystems—such as navigation, flight control, or sensors—to be accurately processed by onboard computers and digital systems.
Each DEI receiver includes internal filtering, voltage threshold detection, and lightning protection circuitry that is compliant with DO-160 standards, providing system-level resilience and reducing the need for external protection components.
