GENERAL DESCRIPTION
The HI-3182, HI-3183, HI-3184, HI-3185, HI-3186, HI-3187 and
HI-3188 bus interface products are silicon gate CMOS devices
designed as a line driver in accordance with the ARINC 429 bus
specifications. In addition to being functional upgrades of Holt's
HI-8382 & HI-8383 products, they are also alternate sources for
the HS-3182 ( Intersil/Harris), the RM3182 (Fairchild /Raytheon)
and a variety of similar line driver products from other manufac-
turers.
Inputs are provided for clocking and synchronization. These
signals are AND'd with the DATA inputs to enhance system
performance and allow the HI-318X series of products to be
used in a variety of applications. Both logic and synchronization
inputs feature built-in 2,000V minimum ESD input protection as
well as TTL and CMOS compatibility.
The differential outputs of the HI-318X series of products are
programmable to either the high speed or low speed ARINC 429
output rise and fall time specifications through the use of two
external capacitors. The output voltage swing is also adjustable
by the application of an external voltage to the VREF input.
Products with 0, 13 or 37.5 ohm resistors in series with each
ARINC output are available. In addition, the HI-3182, HI-3184
and HI-3187 products also have a fuse in series with each
output.
The HI-318X series of line drivers are intended for use where
logic signals must be converted to ARINC 429 levels such as
when using an ASIC, the HI-3282/HI-8282A ARINC 429 Serial
Transmitter/Dual Receiver, the HI-6010 ARINC 429 Transmit-
ter/Receiver or the HI-8783 ARINC Interface Device.
Holt
products are readily available for both industrial and military
applications. Please contact the Holt Sales Department for
additional information.

FUNCTIONAL DESCRIPTION
The SYNC and CLOCK inputs establish data synchronization
utilizing two AND gates, one for each data input (figure 2).
Each logic input, including the power enable (STROBE) input,
are TTL/CMOS compatible.
Figure 1 illustrates a typical ARINC 429 bus application.
Three power supplies are necessary to operate the HI-3182;
typically +15V, -15V and +5V. The chip also works with ±12V
supplies. The +5V supply can also provide a reference
voltage that determines the output voltage swing. The
differential output voltage swing will equal 2V
REF
. If a value of
V
REF
other than +5V is needed, a separate +5V power supply
is required for pin V
1
.
With the DATA (A) input at a logic high and DATA (B) input at a
logic low, A
OUT
will switch to the +V
REF
rail and B
OUT
will
switch to the -V
REF
rail (ARINC HIGH state). With both data
input signals at a logic low state, the outputs will both switch to
0V (ARINC NULL state).
The driver output impedance, R
OUT
, is nominally 75, 26 or 0
ohms depending on the option chosen. The rise and fall times
of the outputs can be calibrated through the selection of two
external capacitor values that are connected to the C
A
and C
B
input pins. Typical values for high-speed operation
(100KBPS) are C
A
= C
B
= 75pF and for low-speed operation
(12.5 to 14KBPS) C
A
= C
B
= 500pF.
The C
A
and C
B
pins swing between +5V and ground allowing
the switching of capacitor values with an external single-
supply analog switch.
The ARINC outputs can be put in a tri-state mode by applying
a logic high to the STROBE input pin. If this feature is not
being used, the pin should be tied to ground. The STROBE
function is not available in the 14 & 16-pin SOIC package
configurations where the pin is internally connected to
ground.
The ARINC outputs of the HI-3182, HI-3184 and HI-3187 are
protected by internal fuses capable of sinking between 800 -
900 mA for short periods of time (125
m
s).
The Vref pin has an internal pull-up resistor to V+, allowing the
use of a simple external zener diode to set the reference
voltage.
POWER SUPPLY SEQUENCING
The power supplies should be controlled to prevent large
currents during supply turn-on and turn-off. The
recommended sequence is +V followed by V
1
, always
ensuring that +V is the most positive supply. The -V supply
is not critical and can be asserted at any time.

Notes:
1. All data taken in still air on devices soldered to a 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. 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.
4. Similar results would be obtained with A
OUT
shorted to B
OUT
.
5. For applications requiring survival with continuous short circuit, operation above Tj = 175°C is not recommended.
6. Data will vary depending on air flow and the method of heat sinking employed.
7. Current values listed are for each of the +V and -V supplies.
HEAT SINK - ESOIC PACKAGES
Both the 14-pin and 16-pin thermally enhanced SOIC
packages are used for HI-318X products. These ESOIC
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.
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.
