MISSION VIEJO, Calif., 12 Nov. 2010. Holt Integrated Circuits Inc. in Mission Viejo, Calif., is introducing an ARINC 429avionics databus line driver powered by one 3.3-volt power supply. The HI-8596 automatically generates all ARINC 429 voltage levels on-chip, eliminating the need for negative voltage supplies or inverters typically found in ARINC 429 bus driver designs, company officials say.
The HI-8596 operates from one 3.3-volt supply using four external capacitors, resulting in low power dissipation and space saving. The device also has tri-state high-impedance outputs when both data inputs are taken high, enabling several line drivers to be connected to a common bus.
Different outputs are available for implementing external lightning protection, which meet the requirements of DO-160F, Level 3, waveforms 3, 4, 5A and 5B, Holt officials say.
An ARINC 429 application solution at 3.3 volts is possible by pairing the HI-8596 with Holt's DO-254 certifiable HI-3586 protocol integrated circuit. The HI-8596 is available in compact 16-pin SOIC and QFN packages. For more information contact Holt Integrated Circuits online at www.holtic.com.
