HI-8282  
ARINC 429 SERIAL TRANSMITTER AND DUAL RECEIVER  
September 2006  
GENERALDESCRIPTION  
FEATURES  
! ARINC specification 429 compliant  
! 16-Bit parallel data bus  
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 theARINC 429 specifications for loading,  
level detection, timing, and protocol. The transmitter  
section provides the ARINC 429 communication protocol.  
An external line driver such as the Holt HI-8585 or HI-3182  
is required to translate the 5 volt logic outputs toARINC 429  
drive levels.  
! Direct receiver interface to ARINC bus  
! Timing control 10 times the data rate  
! Selectable data clocks  
! Receiver error rejection per ARINC  
specification 429  
! Automatic transmitter data timing  
! Self test mode  
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 andTTL.  
! Parity functions  
! Low power, single 5 volt supply  
! Industrial & full military temperature ranges  
! DSCC SMD part number  
Timing of all the circuitry begins with the master clock input,  
CLK. For ARINC 429 applications, the master clock  
frequency is 1 MHz.  
PIN CONFIGURATION (Top View)  
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-8282 examines 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 8ARINC 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 theARINC transmission within the required  
resolution.
