ARINC 429 Dual Line Receiver

Holt Integrated Circuits 

HI-8483

TYPICAL APPLICATIONS

APPLICATIONS

The standard connections for the HI-8483 are shown in

Figure 2. Decoupling of the supply should be done near the

IC to avoid propagation of noise spikes due to switching

transients. The ground (GND) connection should be sturdy

and isolated from large switching currents to provide a quiet

ground reference.

The HI-8483 can be used with HI-8570 or HI-8585 Line

Drivers to provide a complete analog ARINC 429 interface

solution. A simple application, which can be used in

systems requiring a repeater type circuit for long

transmissions or for test interfaces, is given in Figure 3.

More HI-8570 or HI-8585 drivers may be added to test

multiple ARINC channels, as shown.
