Single-Rail ARINC 429 Differential Line Driver
GENERAL DESCRIPTION
PIN CONFIGURATION (TOP VIEW)
The HI-8592 bus interface product is a silicon gate
CMOS device designed as a line driver in accordance
with the ARINC 429 bus specifications. The part includes a negative voltage converter allowing it to operate from a single +5V supply using only two external capacitors. The part also features high-impedance outputs
(tri-state) when both data inputs are taken high, allowing
multiple line drivers to be connected to a common bus.

The HI-8593 and HI-8594 are reduced pin count versions of HI-8592 which do not incorporate the negative
voltage converter. These devices are compatible with
Holt’s existing HI-8570 and HI-8571 respectively, with
the added advantage of the tri-state outputs. For even
smaller board footprint, versions are also available in
leadless, surface mount QFN-style packages.

FUNCTIONAL DESCRIPTION
Figure 1 is a block diagram of the line driver. The chip
requires a positive 5V supply at V+. The negative 5V
supply at V- may be from an external source or may be
provided using the on-chip negative rail generator by
connecting the two external capacitors, CFLY and COUT.
Currents for slope control are set by on-chip resistors.
The TX0IN and TX1IN inputs receive logic signals from
a control transmitter chip such as the HI-3584. 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 selected by the
SLP pin. If the SLP pin is high, the capacitor is nominally
charged from 10% to 90% in 1.5μs. If SLP is low, the
rise and fall times are 10μs.
The reduced pin-count HI-8593 and HI-8594 require an
external -5V supply.
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-859x family.
The HI-8593 has 37.5 ohms in series with each TXOUT
output and the HI-8594 has 5 ohms in series with each
AMP output. The AMP outputs are for applications
where external series resistance is required, typically
for lightning protection devices. Both output types are
available on the HI-8592. Holt Application Note AN-300
describes suitable lightning protection schemes.
All devices feature tri-stateable outputs to allow multiple
line drivers to be connected to the same ARINC 429
bus. Setting TX1IN and TX0IN both to a logic “1” puts
the outputs in the high-impedance state.
The HI-8592 family of line drivers are built using highspeed CMOS technology. Care should be taken to ensure the V+ and V- supplies are locally decoupled to reduce noise. An application example is shown in Figure
2.

NOTE: Stresses above absolute maximum ratings or outside
recommended operating conditions may cause permanent
damage to the device. These are stress ratings only. Operation at the limits is not recommended.
Note: The HI-8592 family of drivers are available in small-footprint, thermally enhanced SOIC and QFN (chip-scale) packages. These packages include 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.

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

Data will vary depending on air flow and the method of heat sinking employed.
