DESCRIPTION
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 part of
the output resistance so that external series protection
circuits can add their resistances.
The HI-8585 or the HI-8586 along with the HI-8588 line
receiver offer the smallest options available to get on and
off the ARINC bus.
