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 theARINC 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
• Military processing available

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