GENERAL DESCRIPTION
The HI-8581 and HI-8589 from Holt Integrated Circuits are silicon gate CMOS devices for interfacing a 16-bit parallel data bus directly to the ARINC 429 serial bus. Both devices provide two receivers, an independent transmitter and line driver capability in a single package. 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 and the line driver circuits provide the ARINC 429 output 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.
The HI-8581 has 37.5 ohms in series with each line driver output. The HI-8589 provides the option to bypass most of the internal output resistance so that external series resistance may be added for lighting protection and still match the 75 ohm characteristic impedance of the ARINC bus.

FEATURES
• ARINC specification 429 compliant
• Direct receiver and transmitter interface to ARINC bus in a single device
• 16-Bit parallel data bus
• Timing control 10 times the data rate
• Selectable data clocks
• Receiver error rejection per ARINC 429 standard
• Automatic transmitter data timing
• Parity functions
• Low power
• Self test mode
• Industrial & extended temperature ranges
