HI-3282

July 2013 HI-3282, HI-3282B ARINC 429 Serial Transmitter and Dual Receiver GENERAL DESCRIPTION The HI-3282 is a silicon gate CMOS device for interfacing the ARINC 429 serial data bus to a 16-bit parallel data bus. Two receivers and an independent transmitter are provided. The receiver input circuitry and logic are designed to meet the ARINC 429 specifications for loading, level detection, timing, and protocol. The ARINC inputs of the HI-3282-10 configurations also have internal lightning protection to DO-160D, Level 3. The transmitter section provides the ARINC 429 communication protocol. An external ARINC 429 Line Driver such as the Holt HI-3182 or HI-8585 is required to translate the 5 volt logic outputs to ARINC 429 drive levels. The 16-bit parallel data bus exchanges the 32-bit ARINC data word in two steps when either loading the transmitter or interrogating the receivers. The data bus interfaces with CMOS and TTL. Timing of all the circuitry begins with the master clock input, C...
