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. A logic input is provided to control the slope of the differential output signal. Timing is set by on-chip resistor and capacitor and tested to be within ARINC requirements. The HI-8585 has 37.5 ohms in series with each line driver output. The HI-8586 provides the option to bypass most of the output resistance so that series protection circuits can add their resistances. |
