HI-8585PSI Integrated Circuits

ARINC 429 Driver 2TX 100Kbps 8Pin SOIC N EP

DESCRIPTION

The HI-8585 and HI-8586 are CMOS integrated circuits designed to directly drive the ARINC 429 bus in an8 pin package. Two logic inputs controla differential voltage between the output pins producinga +10 volt One,a -10 volt Zero, anda0 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.
