HI8282 Datasheet | Holt Integrated Circuits

h S ata D.w w w HI-8282 January 2001 GENERAL DESCRIPTION The HI-8282 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 transmitter section provides the ARINC 429 munication protocol. Additional interface circuitry such as the Holt HI-8382 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...
