ARINC 429 Bus Interface Line Driver
Circuit
The HS-3182 is a monolithic dielectric ally isolated bipolar
differential line driver designed to meet the specifications of
ARINC 429. This device is intended to be used with a
companion chip, HS-3282 CMOS ARINC Bus Interface
Circuit, which provides the data formatting and processor
interface function.
All logic inputs are TTL and CMOS compatible. In addition to
the DATA (A) and DATA (B) inputs, there are also inputs for
CLOCK and SYNC signals which are AND’d with the DATA
inputs. This feature enhances system performance and
allows the HS-3182 to be used with devices other than the
HS-3182.
Three power supplies are necessary to operate the HS-3182:
+V = +15V ±10%, -V = -15V ±10%, and V1 = 5V ±5%. VREF is
used to program the differential output voltage swing such that
VOUT (DIFF) = ±2VREF. Typically, VREF = V1 = 5V ±5%, but a
separate power supply may be used for VREF which should
not exceed 6V.
The driver output impedance is 75Ω ±20% at +25°C. Driver
output rise and fall times are independently programmed
through the use of two external capacitors connected to the CA
and CB inputs. Typical capacitor values are CA = CB = 75pF for
high-speed operation (100kBPS), and CA = CB = 300pF for
low-speed operation (12kBPS to 14.5kBPS). The outputs are
protected against overvoltage and short circuit as shown in the
Block Diagram. The HS-3182 is designed to operate over an
ambient temperature range of -55°C to +125°C, or -40°C to
+85°C.

NOTE: The rise and fall time of the outputs are set to ARINC specified values by CA and CB. Typical CA = CB = 75pF for high speed and 300pF for
low speed operation. The output HI and low levels are set to ARINC specifications by VREF.
