HI-8585 Overview
The HI-8585 and HI-8586 are CMOS integrated circuits designed to directly drive the ARINC 429 bus in an 8 pin package. Two logic inputs control a differential voltage between the output pins producing a +10 volt One, a -10 volt Zero, and a 0 volt Null. The CMOS/TTL control inputs are translated to ARINC specified amplitudes using on board zeners.
