The HI-8685 and HI-8686 are system components for interfacing incoming ARINC 429 signals to 16-bit parallel data using proven +5V analog/digital CMOS technology. Both products incorporate the digital logic and analog line receiver circuitry in a single device. The receivers on the HI-8685 and the HI-8686 connect directly to the ARINC 429 Bus and translate the incoming signals to normal CMOS levels. Internal comparator levels are set just below the standard 6.5 volt minimum data threshold and just above the standard 2.5 volt maximum null threshold. The -10 version of the HI-8685 allows the incorporation of an external 10K resistance in series with each ARINC input for lightning protection without affecting ARINC level detection. |
