ARINC 429 DIFFERENTIAL LINE DRIVER
GENERAL DESCRIPTION
PIN CONFIGURATION
The HI-8382 and HI-8383 bus interface products are silicon
gate CMOS devices designed as a line driver in accordance
with the ARINC 429 bus specifications.
VREF 1
The differential outputs of the HI-8382 are independently
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. The HI-8382 has on-chip Zener diodes in series with a
fuse to each differential output protecting the ARINC bus from
an overvoltage failure. The outputs each have a series
resistance of 37.5 ohms. The HI-8383 is identical to the HI8382 except that the series resistors are 13 ohms and the
overvoltage protection circuitry has been eliminated.

Inputs are provided for clocking and synchronization. These
signals are AND'd with the DATA inputs to enhance system
performance and allow the HI-8382 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.

FUNCTION
The updated HI-318X and HI-8585 ARINC 429 line drivers are
recommended for all new designs where logic signals must be
converted to ARINC 429 levels such as a user ASIC, the
HI-3282 or HI-8282A ARINC 429 Serial Transmitter/Dual
Receiver, the HI-6010 ARINC 429 Transmitter/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,
including data sheets for any of the Holt products mentioned
above.

FUNCTIONAL DESCRIPTION
switch capacitors must be done with analog switches that
allow voltages below their ground.
The SYNC and CLOCK inputs establish data synchronization
utilizing two AND gates, one for each data input. Each logic
input, including the power enable (STROBE) input, are
TTL/CMOS compatible. Besides reducing chip current drain,
STROBE also floats each output. However the overvoltage
fuses and diodes of the HI-8382 are not switched out.
Both ARINC outputs of the HI-8382 are protected by internal
fuses capable of sinking between 800 - 900 mA for short
periods of time (125µs).
Figure 1 illustrates a typical ARINC 429 bus application.
Three power supplies are necessary to operate the HI-8382;
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 2VREF. If a value of
VREF other than +5V is needed, a separate +5V power supply
is required for pin V1.
With the DATA (A) input at a logic high and DATA (B) input at a
logic low, AOUT will switch to the +VREF rail and BOUT will
switch to the -VREF rail (ARINC HIGH state). With both data
input signals at a logic low state, the outputs will both switch to
0V (ARINC NULL state).
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 V1, always ensuring that
+V is the most positive supply. The -V supply is not critical
and can be asserted at any time.

INPUTS
The driver output impedance, ROUT, is nominally 75 ohms.
The rise and fall times of the outputs can be calibrated through
the selection of two external capacitor values that are
connected to the CA and CB input pins. Typical values for
high-speed operation (100KBPS) are CA = CB = 75pF and for
low-speed operation (12.5 to 14KBPS) CA = CB = 500pF.
The driver can be externally powered down 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 CA and CB pins are inputs to unity gain amplifiers.
Therefore they must be allowed to swing to -5V. Provision to

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. 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. Similar results would be obtained with AOUT shorted to BOUT.
6. For applications requiring survival with continuous short circuit, operation above Tj = 175°C is not recommended.
7. Data will vary depending on air flow and the method of heat sinking employed.
