DESCRIPTION

FEATURES

(DS8585 Rev. D)

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.

Direct ARINC 429 line driver

interface in a small package

On-chip zener to set output levels

On-chip line driver slope control and

selection by logic input

Low current 12 to 15 volt supplies

CMOS / TTL logic pins

Plastic and ceramic package options -

surface mount and DIP

Themally enhanced SOIC packages

... 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 applica- tions where more series resistance is added externally, typically for lightning protection devices ...
