DESCRIPTION
FEATURES
(DS8585 Rev. E)
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 most
of the output resistance so that 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.

... A unity gain buffer receives the internally generated slopes and differentially drives the ARINC line. Current is limited by the series output resistors at each pin. There are no fuses at the outputs of the HI-8585 as exists on the HI-8382. The HI-8585 has 37.5 ohms in series with each output. The HI-8586 has 10 ohms in series. The HI-8586 is for applications where more series resistance is added exter- nally, typically for lightning protection devices ...
