Holt Integrated Circuit's 3.3-volt ARINC 429 line driver complies with DO-160G EMI/EMC requirements

Posted by John McHale
MISSION VIEJO, Calif. 5 March 2011. Holt Integrated Circuits announced compliance of its latest 3.3-volt ARINC 429 line driver, HI-8596, with the electromagnetic interference/electromagnetic compatibility (EMI/EMC) requirements of RTCA/DO-160G, Section 21, Category P. This specification provides a standardized test methodology for environmental testing of airborne equipment such as cockpit instruments and flight controls.

Holt also demonstrated the part's robustness to transients and lightning strikes by meeting the requirements of DO-160G, Level 3, waveforms 3, 4, 5A, and 5B.
The HI-8596 operates from a single 3.3-volt supply using only four external capacitors. This allows easy integration with field programmable gate arrays (FPGAs) without the need for additional supplies and provides a compact and cost effective solution. 
All testing was performed by an accredited external lab and a copy of the final test report is available in Application Note AN-135. 
"This independent testing has demonstrated the capability of HI-8596 to meet the most stringent EMI/EMC requirements,”"says Anthony Murray, director of business development at Holt. "In addition, the possibility of a single supply makes HI-8596 a great choice for FPGA or 3.3 volt dual redundant ARINC 429 applications."
The HI-8596 is available in a 16-pin SOIC package or a more compact 16-pin QFN. Samples and a demonstration kit are available upon request.
