Holt product design and testing are performed in-house, providing a cost-effective, innovative mixed-signal solution for microprocessor-based embedded applications. Holt's product line includes MIL-STD-1553, ARINC 429, discrete to digital sensing, controller area network (CAN), analog switches and RS-485/422. There are hundreds of applications for these products in the design, from flight control and engine management to onboard entertainment systems and test equipment.

For over 40 years, Holt Integrated Circuits, Inc. has provided analog and mixed signal IC data bus solutions to the avionics industry, supplying more than 400 manufacturers worldwide in a wide variety of applications such as flight control, engine management, navigation, communications, safety systems and in-flight entertainment systems. In addition, Holt also leverages versions of its avionics products in other markets requiring highly reliable and robust components, such as down-hole drilling and industrial process automation.


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 ICs 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.

Holt's ARINC 429 databus and LCD drivers are intended for both commercial and military applications. Ranging from Jet Fighter to 747, Holt ICs have been used at the heart of Flight Control, Navigation, Engine Management, Communications, Safety equipment, and In-Flight Entertainment systems. Holt has established long term cooperation relationship with more than 250 avionics manufacturers for high quality and excellent technology. Holt's ARINC 429 products can be available not only in traditional high-reliability ceramic packages but also in a state-of-the-art small footprint, thermally enhanced plastic surface mount formats. Besides, Holt has set foot in the new application area-MIL-STD-1553. The HI-1567PSI, the first product the company developed, is the smallest 5 V dual transceiver in the world. Holt is dedicated to providing the customer's products with size, performance, and cost advantages.
