ARINC 429 LINE DRIVER
August 2006
DESCRIPTION
PIN CONFIGURATION
The HI-8585 and HI-8586 are CMOS integrated circuits
designed to directly drive the ARINC 429 bus in an 8-pin
package. Two logic inputs control a differential voltage
between the output pins producing a +10 volt One, a
-10 volt Zero, and a 0 volt Null.

The CMOS/TTL control inputs are translated to ARINC
specified amplitudes using on board zeners. A logic input
is provided to control the slope of the differential output
signal. Timing is set by on-chip resistor and capacitor and
tested to be withinARINC requirements.
SUPPLY VOLTAGES
The HI-8585 has 37.5 ohms in series with each line driver
output. The HI-8586 provides the option to bypass part of
the output resistance so that external series protection
circuits can add their resistances.
V+ = 12V to 15V
V- = -12V to -15V
The HI-8585 or the HI-8586 along with the HI-8588 line
receiver offer the smallest options available to get on and
off theARINC bus.

HI-8585, HI-8586
FUNCTIONAL DESCRIPTION
Figure 1 is a block diagram of the line driver. The +5V and
-5V levels are generated internally using on-chip zeners.
Currents for slope control are set by zener voltages across
on-chip resistors.
A unity gain buffer receives the internally generated slopes
and differentially drives the ARINC line. Current is limited
by the series output resistors at each pin. There are no
fuses at the outputs of the HI-8585 as exists on the HI-
8382.
The TX0IN and TX1IN inputs receive logic signals from a
control transmitter chip such as the HI-6010, HI-3282 or
HI-8282. TXAOUT and TXBOUT hold each side of the
ARINC bus at Ground until one of the inputs becomes a
One. If for example TX1IN goes high, a charging path is
enabled to 5V on an “A” side internal capacitor while the
“B” side is enabled to -5V. The charging current is se-
lected by the SLP1.5 pin. If the SLP1.5 pin is high, the
capacitor is nominally charged from 10% to 90% in 1.5µs.
If SLP1.5 is low, the rise and fall times are 10µs.
The HI-8585 has 37.5 ohms in series with each output and
the HI-8586 has 2 ohms in series with each output. The
HI-8586 is for applications where external series resis-
tance is required, typically for lightning protection devices.
Both the HI-8585 and HI-8586 are built using high-speed
CMOS technology. Care should be taken to ensure the
V+ and V- supplies are locally decoupled and that the
input waveforms are free from negative voltage spikes
which may upset the chip’s internal slope control circuitry.

Notes:
1. All data taken in still air on devices soldered to single layer copper PCB (3" X 4.5" X .062").
2. At 100% duty cycle, 15V power supplies. For 12V power supplies multiply all tabulated values by 0.8.
3. Low Speed: Data Rate = 12.5 Kbps, Load: R = 400 Ohms, C = 30 nF.
4. High Speed: Data Rate = 100 Kbps, Load: R = 400 Ohms, C = 10 nF. Data not presented for C = 30 nF
as this is considered unrealistic for high speed operation.
5. 8 Lead Plastic ESOIC (Thermally enhanced SOIC with built in heat sink). Heat sink not soldered to the PCB.
6. 8 Lead Plastic ESOIC (Thermally enhanced SOIC with built in heat sink). Heat sink soldered to the PCB.
7. Similar results would be obtained with TXAOUT shorted to TXBOUT.
8. For applications requiring survival with continuous short circuit, operation above Tj = 175°C is not recommended.
9. Data will vary depending on air flow and the method of heat sinking employed.
10. Current values are per supply.
HEAT SINK - ESOIC PACKAGES
An 8-pin thermally enhanced SOIC package is used for the
HI-8585/HI-8586 products. The ESOIC package includes
a metal heat sink located on the bottom surface of the
device. This heat sink should be soldered down to the
printed circuit board for optimum thermal dissipation. The
heat sink is electrically isolated from the chip and can be
soldered to any ground or power plane. However, since
the chip’s substrate is at V+, connecting the heat sink to
this power plane is recommended to avoid coupling noise
into the circuit.
