Enhanced Octal ARINC 429 Receiver

Friday, October 7, 2022

Aliso Viejo, CA (October 6, 2022) – Holt Integrated Circuits Holt Integrated Circuits today announced the release of a new 8-channel ARINC 429 line receiver. The device, HI-35981,  is an enhanced version of Holt’s well-established HI-35980 (HI-3598) family, with additional features and functionality. The user-programmable label filtering capability has been expanded from 16 labels to all 256 labels, and the 4-word deep receive FIFO has been increased to 32 words deep. In addition, a 32-word deep transmit FIFO has been added, significantly increasing the transmit capability from the single-word buffer on the existing device. 

Each receive channel has an integrated line receiver, enabling direct connection to an ARINC 429 bus. The user has the option on each channel to use the built-in input resistor or use an external resister to provide addition flexibility for external lightning protection. The digital transmit channel also has a digital output pin to set the data rate on an external line driver, such as Holt’s lightning-protected HI-8597 or galvanically isolated HI-8598

“This enhanced device provides our customers with additional functionality and flexibility for data management in ARINC 429 networks,” said George Noh, Director of Sales and Marketing at Holt. “The integration of 8 receive channels in a single compact IC greatly reduces customer component count, size and cost.” 

The device is available in industrial −40oC to +85oC and extended −55oC to +125oC temperature ranges with optional burn-in at the higher temperature. Samples are available from Holt on request.
