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.
