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.
The Holt HI-8685 and HI-8686 are system components designed for interfacing incoming ARINC 429 signals to 16-bit parallel data using +5V analog/digital CMOS technology. These devices incorporate digital logic and analog line receiver circuitry in a single package, eliminating the need for external level detection circuits.
The device requires a +5V power supply with a tolerance of +/-10%.
The minimum word gap time is between 16 and 17 clock cycles of the GAPCLK signal.
A valid ARINC One/Zero input sets a latch, while a Null input resets the latch.
