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.

Each independent receiver monitors the data stream with

a sampling rate 10 times the data rate. The sampling rate

is software selectable at either 1MHz or 125KHz. The

results of a parity check are available as the 32nd ARINC

bit. The HI-8581 and HI-8589 examine the null and data

timings and will reject erroneous patterns. For example,

with a 125 KHz clock selection, the data frequency must

be between 10.4 KHz and 15.6 KHz.

The transmitter has a First In, First Out (FIFO) memory to

store 8 ARINC words for transmission. The data rate of

the transmitter is software selectable by dividing the

master clock, CLK, by either 10 or 80. The master clock is

used to set the timing of the ARINC transmission within the

required resolution.
