HI-8588
ARINC 429 LINE RECEIVER
August 2006
DESCRIPTION
PIN CONFIGURATION
The HI-8588 is an ARINC 429 bus interface receiver and is
available in a SO 8 pin package. The technology is
analog/digital CMOS. The circuitry requires only a 5 volt
supply.
The ARINC bus can be connected directly to the chip. The
typical 10 volt differential signal is translated and input to a
window comparator and latch. The comparator levels are
just below the standard 6.5 volt minimum ARINC data
threshold and just above the standard 2.5 volt maximum
ARINC null threshold.
The TESTA and TESTB inputs bypass the analog for
testing purposes. Also if TESTA and TESTB are both taken
high, the analog powers down and the digital outputs tristate allowing wire-or possibilities.
Please refer to the HI-8588-10 for applications where an
external resistance in series with the ARINC inputs is
required for lightning protection or when the digital outputs
need to be a logic zero rather than open circuit when
TESTA and TESTB are both high.
See Holt Application Note AN-300 for more information on
lightning protection.

FUNCTIONAL DESCRIPTION
RECEIVER
The status of the ARINC receiver input is latched. A
Null input resets the latches and a One or Zero input
sets the latches.
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 have series resistors, typically 35K ohms. They connect to level translators whose
resistance to Ground is typically 10K ohms. Therefore, any
series resistance added to the inputs will affect the voltage
translation.
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, then
the receiver is powered down and the output pins float.
The powerdown does not disconnect the internal resistors at the ARINC input.
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 VCC and Ground. The nominal settings correspond
to a One/Zero amplitude of 6.0V and a Null amplitude of
3.3V.
