[HOLT INTEGRATED CIRCUITS]
The HI-8282 isa silicon gate CMOS device for interfacing the ARINC 429 serial data bus toa 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 transmitter section provides the ARINC 429 communication protocol. Additional interface circuitry such as the Holt HI-8382 is required to translate the5 volt logic outputs to ARINC 429 drive levels.

APPLICATIONS

• Avionics data communication
• Serial to parallel conversion
