HS-3182 FN2963
Rev 3.00
May 30, 2008 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. Features RoHS/Pb-free Available for SBDIP Package (100% Gold
Termination Finish) TTL and CMOS Compatible Inputs Adjustable Rise and Fall Times via Two External
Capacitors Programmable Output Differential Voltage via VREF Input Operates at Data Rates Up to 100k Bits/s Output Short Circuit Proof and Contains Overvoltage
Protection Three power supplies are necessary to operate the HS-3182:
+V = +15V В±10%, -V = -15V В±10%, and V1 = 5V В±5%. VREF is
used to program the differential output voltage swing such that
VOUT (DIFF) = В±2VREF. Typically, VREF = V1 = 5V В±5%, but a
separate power supply may be used for VREF which should …
