HI-6011
ARINC 429
Transmitter / Dual Receiver for 8-Bit Bus
October 2012
GENERAL DESCRIPTION
FEATURES
•ꢀ Single +5V supply
The HI-6011 is a CMOS integrated circuit designed to
interface the avionics ARINC 429 data bus to an 8-bit
port. It contains two receivers and one transmitter. They
operate independently except for the parity option and
the selected clock rate. The receiver demands that
the incoming data meet the standard protocol and the
transmitter outputs a standard protocol stream.
•ꢀ ARINC 429 protocol controller with 8-bit parallel
host interface
•ꢀ Automatic label recognition option
•ꢀ Programmable parity option
•ꢀ TransmitꢀFIFOꢀforꢀupꢀtoꢀfiveꢀARINCꢀ429ꢀmessagesꢀ
•ꢀ CMOS / TTL logic pins
TheꢀHI-6011ꢀprovidesꢀflexibleꢀoptionsꢀforꢀinterfacingꢀtoꢀ
the user system. The controlling processor can operate
both the receiver and transmitter either by using hard
wiredꢀflagsꢀandꢀgatesꢀatꢀtheꢀpinsꢀorꢀbyꢀusingꢀsoftwareꢀ
reads and writes of internal registers or a combination
thereof.
•ꢀ Industrial and Extended temperature ranges
•ꢀ Burn-in available
PIN CONFIGURATION (TOP VIEW)
The chip is programmable to operate with single 8-bit
bytes where successive writes and reads are used to
receive or transmit complete 32 bit words.

The HI-6011 is a 5 volt chip that will require data
translation from and to the ARINC bus using external
line drivers and line receivers. The HI-8591 line receiver
is available for the receiver side and the single supply
HI-8592 line driver is available for the transmitter side.
