24-Channel ARINC 429 Data Management IC with Integrated Line Receivers
1/16/2018

Holt Integrated Circuits today expanded its ARINC 429 data management capability with the announcement of five new devices. The HI-3220 family is capable of managing, storing and forwarding avionics data between 16 ARINC 429 receive channels and 8 ARINC 429 transmit channels in a tiny 10x10mm² footprint. Integrated line receivers and a compact serial peripheral host interface (SPI) save significant amounts of space at such high channel densities, making these devices ideal for multi-channel applications such as data concentrators. An option for 8 receive and 4 transmit channels is also available in an even smaller, cost effective 7x7mm² QFN package footprint. Read more
