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.
