GENERALDESCRIPTION  
FEATURES  
! ARINC specification 429 compatible  
! 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 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 the 5 volt logic outputs to ARINC 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 tw o steps when either loading the transmitter  
or interrogating the receivers. The data bus interfaces with  
CMOS and TTL.  
! Parity functions  
! Low power, single 5 volt supply  
! Industrial & full military temperature ranges  
! DESC 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.  
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  
se lection, the data frequency must be between 10.4 KHz  
and 15.6 KHz.  
PIN CONFIGURATION (Top View)  
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.
