Line Driver

December 7, 2010

Holt Integrated Circuits (Mission Viejo, CA) has introduced the HI-8596 line driver that 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. The HI-8596 operates from a single +3.3V supply using four external capacitors. The device also features high-impedance outputs (tri-state) when both data inputs are taken high, enabling multiple line drivers to be connected to a common bus. Different outputs are available for implementation of external lightning protection, allowing the requirements of DO-160F, Level 3, waveforms 3, 4, 5A and 5B to be satisfied. The HI-8596 is available in compact 16-pin SOIC and QFN packages.
