ARINC 429 avionics databus interface from Holt meets EMI/EMC guidelines of RTCA/DO-160G

April 13, 2011
MISSION VIEJO, Calif., 13 April 2011. Holt Integrated Circuits Inc. in Mission Viejo, Calif., is announcing compliance of the company's HI-8592 5-volt ARINC 429 avionics databus line driver with the electromagnetic interference and electromagnetic compatibility guidelines of the RTCA/DO-160G, Section 21, Category P industry standard. Compliance means the Holt HI-8592 can operate reliably in cockpit instruments, flight controls, and other avionics applications with strict EMI and EMC requirements.

MISSION VIEJO, Calif., 13 April 2011. Holt Integrated Circuits Inc. in Mission Viejo, Calif., is announcing compliance of the company's HI-8592 5-volt ARINC 429avionics databus line driver with the electromagnetic interference and electromagnetic compatibility guidelines of the RTCA/DO-160G, Section 21, Category P industry standard.

Compliance means the Holt HI-8592 can operate reliably in cockpit instruments, flight controls, and other avionics applications with strict EMI/EMC requirements. ARINC 429 is a widely designed-in avionics databus for commercial aircraft.

The RTCA/DO-160G specification spells out avionics test procedures to ensure that airborne electronics equipment operates reliably in harsh environmental operating conditions. Final test results are available in Holt's application note AN-136.

The Holt HI-8592 avionics databus interface also has demonstrated its ability to stand up to transients and lightning strikes with its compliance to DO-160G, Level 3, waveforms 3, 4, 5A and 5B.

The HI-8592 operates from a 5-volt power supply using two external capacitors. An on-chip negative voltage converter supplies the minus 5-volt levels for ARINC 429 differential signaling.

The HI-8592 is available in a 14-pin small-outline integrated circuit (SOIC) package or a 24-pin QFN. For more information contact Holt online at www.holtic.com.
