DESCRIPTION
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
W
resistance in series with
each ARINC input for lightning protection without affecting
ARINC level detection.
Both products offer high speed 16-bit parallel bus interface,
a 32-bit buffer, and error detection for word length and parity.
A reset pin is also provided for power-on initialization.
