HI-3220
High Density 16Rx / 8Tx or 8Rx / 4Tx ARINC 429 Protocol IC with optional Integrated Line Receivers
GENERAL DESCRIPTION
The HI-3220 from Holt Integrated Circuits is a family of single chip CMOS high density application data management ICs capable of managing, storing and forwarding avionics data messages between sixteen ARINC 429 receive channels and eight ARINC 429 transmit channels. Options for eight receive and four transmit channels are also available in a compact, cost effective 7mm x 7mm QFN package footprint.
The ARINC 429 buses may operate independently - the IC can be programmed to automatically re-format, re-label, re-packetize and re-transmit data from ARINC 429 receive buses to ARINC 429 transmit buses.
