Mission Viejo, CA (June 30, 2010) – Holt Integrated Circuits, a world leader in data bus IC’s for the avionics and military industries, today introduced the world’s first ARINC 429 line driver powered by a single +5V supply. The HI-8592 eliminates the need for negative voltage supplies or inverters which are typically found in ARINC 429 bus driver designs.
The part includes a negative voltage converter, allowing it to operate from a single +5V supply using only two external capacitors. The part also features high-impedance outputs (tri-state) when both data inputs are taken high, allowing multiple line drivers to be connected to a common bus. Different outputs are available for easy implementation of external lightning protection, allowing the requirements of DO-160E, Level 3, waveforms 3, 4, 5A and 5B to be satisfied. The HI-8592 is available in a compact 14-pin ESOIC package.
“The HI-8592 eliminates the need for external negative supplies or inverters, providing a more compact, reliable solution to drive the ARINC 429 bus,” said Anthony Murray, Director of Business Development at Holt.
The HI-8593 and HI-8594 are reduced pin-count variants which have tri-state output capability without the negative voltage converter. These devices are pin-compatible with Holt’s existing HI-8570 and HI-8571 respectively, with the added advantage of tri-state outputs. Samples are available upon request.
