HI-3282  
GENERAL DESCRIPTION  
FEATURES  
! ARINC specification 429 compatible  
! Compatible with Industry-standard alternate  
Parts  
The HI-3282 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 or HI-  
8585 are required to translate the 5 volt logic outputs to  
ARINC 429 drive levels.  
! Small footprint 44 PQFP package option  
! 16-Bit parallel data bus  
! Direct receiver interface to ARINC bus  
! Timing control 10 times the data rate  
! Selectable data clocks  
The 16-bit parallel data bus exchanges the 32-bit ARINC  
da ta word in two steps when either loading the transmitter  
or interrogating the receivers. The data bus interfaces with  
CMOS and TTL.  
! Automatic transmitter data timing  
! Self test mode  
! Parity functions  
! Low power, single 5 volt supply  
! Industrial & full military temperature ranges  
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 transmitter has a First In, First Out (FIFO) memory to  
store 8 ARINC words for transmission. The data ra te 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.
