DESCRIPTION
The HI-8683 and HI-8684 are system components for interfacing incoming ARINC 429 signals to 8-bit parallel
data using proven +5V analog/digital CMOS technology. The HI-8683 is a digital device that requires an external
analog line receiver such as the HI-8482 or HI-8588 between the ARINC bus and the device inputs. The HI-8684
incorporates the digital logic and analog line receiver circuitry in a single device.

FEATURES
Automatic conversion of serial ARINC 429, 575 & 561 data to 8-bit parallel data
High speed parallel 8-bit data bus
Error detection - word length and parity
Reset input for power-on initialization
On-chip line receiver option (HI-8684)
Input hysteresis of at least 2 volts (HI-8684)
Test inputs bypass analog inputs (HI-8684)
Simplified lightning protection with the ability to add
10 Kohm external series resistors (HI-8684-10)
Plastic package options - surface mount (SOIC), PLCC and DIP
Industrial and extended temperature ranges

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