Product Summary

The HI-8570PSI is 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 HI-8570PSI has 37.5 ohms in series with each line driver output. The HI-8571 provides the option to bypass part of the output resistance so external resistance may be added for lightning protection circuits.
