HI-8477 / HI-8478

The HI-8477 / HI-8478 are ARINC 429 Receivers designed specifically for use without a microprocessor. All configuration and control is programmed via logic level input pins, eliminating the need for a microprocessor or software interface and greatly reducing or eliminating the cost associated with software certification.

The HI-8477 receives ARINC 429 data directly from the bus and makes the data available at 32 digital output pins. The HI-8478 option provides the compliment of HI-8477 digital outputs from the 32-bit ARINC 429 word. ARINC 429 label filtering is defined by 16 digital input pins, defining a maskable label match to enable reception of a single label or group of labels. A PARITY check pin provides the user the option of checking for correct odd parity on incoming ARINC 429 words (PARITY = logic "1"). Incorrect parity words are ignored. If parity checking is turned off (PARITY = logic "0"), all 32 bits of the ARINC word are stored without parity check.  

The receiver inputs are lightning protected to RTCA/DO-160G, Section 22 Level 3 Pin Injection Test Waveform Set A (3 & 4), Set B (3 & 5A) and Set Z (3 & 5B) with the use of only two external resistors. The devices support both high-speed and low-speed ARINC 429 data rates, operating from a 1MHz clock source and a single 3.3V or 5.0V power supply.

The devices are available in a 64-pin PQFP package in industrial (−40oC to +85oC) and extended (−55oC to +125oC) temperature ranges.
