ARINC 429 DUAL LINE RECEIVER

Holt Integrated Circuits 

HI-8482

TYPICAL APPLICATIONS

APPLICATIONS

The standard connections for the HI-8482 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-8482 can be used with HI-8382 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-8382 or HI-8585 drivers may be added to test

multiple ARINC channels, as shown.
