HI-8570 - Holt Integrated Circuits

HI-8570 (HI-8570 / HI-8571) ARINC 429 LINE DRIVER

The HI-8570 and HI-8571 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. A logic input is provided to control the slope of the differential output signal. Timing is set by an on-ch.
