GENERALDESCRIPTION

TheHI-8282AisasilicongateCMOSdeviceforinterfacing
theARINC429serialdatabustoa16-bitparalleldatabus.
Tworeceiversandanindependenttransmitterare
provided.Thereceiverinputcircuitryandlogicare
designedtomeettheARINC429specificationsforloading,
leveldetection,timing,andprotocol.Thetransmitter
sectionprovidestheARINC429communicationprotocol.
AdditionalinterfacecircuitrysuchastheHoltHI-8585,
HI-8586orHI-3182isrequiredtotranslatethe5voltlogic
outputstoARINC429drivelevels.

The16-bitparalleldatabusexchangesthe32-bi tARINC
datawordintwostepswheneitherloadingthetransmitter
orinterrogatingthereceivers.Thedatabusinterfaceswith
CMOSandTTL.

Timingofallthecircuitrybeginswiththemasterclockinput,
CLK.ForARINC429applications,themasterclock
frequencyis1MHz.

Eachindependentreceivermonitorsthedatastreamwitha
samplingrate10timesthedatarate.Thesamplingrateis
softwareselectableateither1MHzor125KHz.Theresults

HI-8282Aexaminesthenullanddatatimingsandwillreject
erroneouspatterns.Forexample ,witha125KHzclock
