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 and 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, TQFP and PLCC

• Military processing available

APPLICATIONS

• Avionics data communication

• Serial to parallel conversion

• Parallel to serial conversion
