Holt Validates new ARINC 429 line receivers with built-in lightning protection

Holt Integrated Circuits, a world leader in data bus IC's for the avionics and military industries, today announced validation of its latest ARINC 429 line receiver family, HI-8450/1 and HI-8454/5, with the lightning requirements of RTCA/DO-160G, Section 22, Level 3 Pin Injection Test Waveform Set A (3 & 4), Set B (3 & 5A) and Set Z (3 & 5B), using no additional external components. Validation was carried out by an independent ISO accredited lab using industry standard procedures and practices. This compliments Holt's single-supply 3.3V ARINC 429 line driver, HI-8597, which was also independently validated to the same lightning requirements with no external components.

The RTCA/DO-160G specification provides a standardized test methodology which is accepted in the avionics industry as the gold standard for environmental testing of airborne equipment. Compliance ensures Holt devices operate reliably in a broad variety of avionics applications with tough environmental requirements and harsh operating conditions.

The HI-8450 is a single channel ARINC 429 line receiver which is pin compatible with Holt's well known HI-8591 and HI-8588. The HI-8454 is pin compatible with the quad channel HI-8444. Both devices operate from either a 3.3V or 5V supply. The built-in lightning protection on these new devices provides additional robustness and eliminates the need for external components when lightning protection is required, translating to board space saving and ultimately reduced cost.

“These DO-254 certifiable devices give our customers confidence to reliably design products for extreme operating environments,” said Scott Paladichuk, Director of Quality at Holt. “The advent of next generation composite aircraft makes these devices even more relevant.”

These devices are available in industrial −40oC to +85oC and extended −55oC to +125oC temperature ranges, with optional burn-in available for extended temperature range devices.
