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.

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-3182 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-3182 or HI-8585 drivers may be added to test
multiple ARINC channels, as shown.
