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.

FEATURES
 • Automatic conversion of serial ARINC 429, 575 & 561 data to 16-bit parallel data
 • High speed parallel 16-bit data bus
 • Error detection - word length parity
 • Reset input for power-on initialization
 • On-chip line receiver
 • Input hysteresis of at least 2 volts
 • Test lnputs bypass analog inputs
 • Simplified lightning protection with the ability to add 10 Kohm external series resistors
 • Small, surface mount, plastic package options: SOIC, PQFP and PLCC
 • Industrial and extended temperature ranges

APPLICATIONS
 • Avionics data communication
 • Serial to parallel conversion
 • Parallel to serial conversion
