The typical 10 volt differential ARINC 429 signal is translated and input to a window comparator and latch. The
comparator levels are set just below the standard 6.5 volt
minimum ARINC data threshold and just above the standard 2.5 volt maximum ARINC null threshold.
See Holt Application Note AN-300 for more information on
lightning protection.

The TESTA and TESTB inputs bypass the analog inputs for
testing purposes. Also if TESTA and TESTB are both taken

The HI-8591 is an ARINC 429 bus interface receiver
designed to operate from a single 3.3 V or 5 V supply. The
part is designed with high-impedance inputs to minimize
bus loading, and has an exceptional input common-mode
performance in excess of +/- 30V, making it immune to
ground offsets around the aircraft. The RINA and RINB
inputs of the standard HI-8591 may be connected directly
to the ARINC 429 bus. To enable external lightning protection circuitry to be added, the HI-8591-40 variant is available. The HI-8591-40 requires only the addition of external
40 KW, ¼ watt resistors in series with RINA and RINB to
allow the part to meet the lightning protection requirements
of DO-160D level 3.

FUNCTIONAL DESCRIPTION
RECEIVER
spond to a One/Zero amplitude of 6.0V and a Null amplitude of 3.3V.
Figure 1 shows the general architecture of the ARINC 429
receiver. The receiver operates off the VCC supply only.
The inputs RINA and RINB each require 140KW of resistance between the ARINC bus and comparator. This resistance is completely on-chip for the HI-8591. In contrast,
the HI-8591-40 has 100 KW on-chip and requires an external 40KW, ¼ watt resistor on each of the ARINC 429 input
pins. The HI-8591-40 device is typically chosen for applications where lightning protection is a requirement.
The status of the ARINC receiver input is latched. A Null
input resets the latches and a One or Zero input sets the
latches.
The logic at the output is controlled by the test signal
which is generated by the logical OR of the TESTA and
TESTB pins. If TESTA and TESTB are both One, the HI8591 outputs are pulled low. This allows the digital outputs of a transmitter to be connected to the test inputs
through control logic for system self-test purposes.
After level translation, the inputs are buffered and become
inputs to a differential amplifier. The amplitude of the differential signal is compared to levels derived from a divider
between V.C. and Ground. The nominal settings corre-

Figure 2 shows a possible application of the
HI-8591 interfacing an ARINC 429 bus input
to a 3.3V ASIC or FPGA. In this example a
HI-8586 ARINC 429 line driver is used to
take 3.3V logic outputs and generate the necessary 10V differential signal for driving an
ARINC 429 bus.
