HI-8571

August 2006 HI-8570, HI-8571 +/- 5V Supply, ARINC 429 LINE DRIVER DESCRIPTION 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-chip resistor and capacitor and tested to be within ARINC requirements. The HI-8570 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. The HI-8570 or the HI-8571 along with the HI-8588 line receiver offer the smallest options available to get on and off theARINC 429 bus. www.DataSheet4U.com FEATURES !
