Mission Viejo, CA (January 28, 2016) - Holt Integrated Circuits introduced today a new Octal ARINC 429 line receiver family with fully integrated lightning protection circuitry. The built-in circuitry ensures compliance with RTCA/DO-160G, Section 22 Level 3 Pin Injection Test Waveform Set A (3 & 4), Set B (3 & 5A) and Set Z (3 & 5B), enabling direct connection to the ARINC 429 bus without external components. All devices operate from a 3.3V or 5.0V supply and have eight independent ARINC 429 line receivers.
The new family comprises three devices, HI-8456, HI-8457 and HI-8458. Each device is designed to operate in a high noise environment, with high input resistance and an input common mode voltage range of ±30V. The HI-8456 and HI-8457 are exact drop-in replacements for DEI1046 and DEI1047 respectively. The HI-8458 is pin-to-pin compatible with Holt’s popular HI-8448 and is also a drop-in replacement for the DEI1148 (44-pin PQFP).
The devices feature protection against non-annunciated system faults (where one side of the ARINC 429 bus transmission line becomes open or shorted to ground) or undefined ARINC 429 voltage levels (ranging between ±2.5V and ±6.5V). All signals received under these conditions are automatically rejected.
“This new line receiver family offers customers a very robust and cost effective solution,” said Anthony Murray, Director of Marketing Communications at Holt. “Integrating lightning protection eliminates many external components and the exceptional common mode voltage range and high input impedance provides reliable operation in high noise environments.”
The HI-8456 and HI-8458 feature test inputs which bypass the analog inputs for testing purposes. This allows the digital outputs of a transmitter to be connected to the test inputs through control logic for system self-test purposes. The HI-8456 has a single test port which controls all 8 channels simultaneously, whereas the HI-8458 has two independent test ports, each controlling a bank of 4 channels.
The devices are available in numerous plastic packages including a 7mm x 7mm QFN, and feature industrial (−40oC to +85oC) and extended (−55oC to +125oC) temperature ranges, with optional burn-in available for the extended temperature range devices.
