About Holt Integrated Circuits

Located in Aliso Viejo, California, Holt Integrated Circuits is a major supplier of Integrated Circuits for the aerospace industry. Holt has manufactured data bus and display drivers for commercial and military users worldwide for over twenty years. From F-16 to A-350, you will find Holt ICs at the heart of Flight Control, Navigation, Engine Management, Communications, Safety equipment and In-Flight Entertainment systems.

Over 400 Avionics manufacturers rely on Holt’s proven track record of customer service, unsurpassed quality and cost-effectiveness, and technical excellence to keep their products at the leading edge.

Holt’s range of ICs supporting the ARINC 429 standard is the widest in the industry, ranging from simple line receivers to full protocol solutions with integrated RAM. The latest line of ARINC 429 products are fully functional terminal ICs designed to operate from a single 3.3V supply, resulting in a significant reduction in system complexity and board space.

Holt MIL-STD-1553 solutions are the smallest and most cost-effective, providing the entire MIL-STD-1553 interface on a single chip. The flagship integrated circuits are widely accepted as the easiest to use in the industry, providing dedicated host interfaces, on-chip RAM, BC/MT/RT and transceiver functions in one small footprint package.

Other products include high-voltage LCD display drivers and ARINC 825 (CAN) data bus products. Holt has the distinction of being the first company in the world to integrate a CAN controller and transceiver on the same IC in a single, compact plastic package.

All of Holt’s Commercial-Off-The-Shelf (COTS) products are DO-254 certifiable, further emphasising its commitment to aerospace customers.
