Based in Aliso Viejo, California, Holt’s technology can be found across a wide range of aircraft—from the F-16 to the A350—powering critical systems including flight control, navigation, engine management, communications, safety equipment, and in-flight entertainment.

More than 400 avionics manufacturers rely on Holt’s proven combination of technical excellence, dependable customer service, superior quality, and cost-effective solutions. The company offers the industry’s broadest portfolio of ARINC 429 devices, spanning simple line receivers to full protocol ICs with integrated RAM. Its latest ARINC 429 terminal solutions operate from a single 3.3-volt supply, reducing system complexity and minimizing board space.

Holt’s MIL-STD-1553 products are among the smallest and most cost-efficient available, integrating the complete 1553 interface—BC/MT/RT, transceiver, on-chip RAM, and dedicated host interfaces—into a single, compact device widely recognized for ease of use.

Additional offerings include high-voltage LCD display drivers and ARINC 825 (CAN) data bus solutions. Notably, Holt was the first company to integrate both a CAN controller and transceiver into one compact IC package.

All Commercial-Off-The-Shelf (COTS) products from Holt are DO-254 certifiable, underscoring the company’s enduring commitment to the aerospace industry.
