World’s first ARINC 429 Line Driver Powered by a Single +5V Supply now available through Advanced Power Components

The HI-8592 line driver eliminates the need for negative voltage supplies or inverters which are typically found in ARINC 429 bus driver designs.



The component includes a negative voltage converter, allowing it to operate from a single +5V supply using only two external capacitors. It 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.



Anthony Murray, Director of Business Development at Holt said:

“The HI-8592 eliminates the need for external negative supplies or inverters, providing a more compact, reliable solution to drive the ARINC 429 bus.”



Kevin Brooks. Technical Manager, APC Hi-Rel, said:

“The Holt HI-8592 is the first ARINC 429 bus driver which can be operated from a single +5V rail. The 8592 derives its own -5V power from an internal “Switch Capacitor DC-DC Inverter” thus removing the need for the designer to provide a -5V power rail. This will result in cost savings for new systems as one power rail is no longer required and will make using ARINC 429 on existing systems without a -5V power supply much simpler.”



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.



The Holt Integrated Circuits line driver is available in the UK through APC-Hi-Rel, the specialist electronic components distributor. Samples are available upon request. For further information, see www.apc-hirel.co.uk or e-mail sales@apc-hirel.co.uk .
