Holt Integrated Circuits today announced the release of the ADK 85104 Evaluation Board, a compact, ready to use platform designed to help engineers rapidly evaluate and characterize Holt’s HI 85104, the world’s first fault isolated quad ARINC 429 line driver. In addition to short circuit protection, the HI-85104 provides integrated 37.5 ohm impedance matched outputs with on chip fuses, output tri state capability when powered on or off, and optional zero Ohm AMP outputs for external lightning protection networks.

Holt Integrated Circuits announced today it will exhibit at the GOMACTech 2026 show, held between March 9 - 12, 2026 at the New Orleans Ernest N. Morial Convention Center, New Orleans, LA, USA.

Holt Integrated Circuits today announced the HI-85104, the world’s first quad ARINC 429 line driver, enabling aerospace designers to achieve higher channel density while reducing board area, component count, and design complexity. The HI-85104 integrates four fully independent ARINC 429 transmit channels into a compact 6 mm × 6 mm QFN package, replacing four discrete single-channel line drivers with a single device.

Holt’s founder, entrepreneur William G. Holt, has published a new memoir, “Engineering Your Career and Life: Lessons Learned While Building a Technology Business”.
