About Holt Integrated Circuits
For over forty years, Holt Integrated Circuits has provided analogue and mixed-signal IC data bus solutions to the avionics industry. Supplying more than 400 manufacturers worldwide, their products support a wide variety of applications such as:
- Flight control
- Engine management
- Safety systems
- 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.
All of Holt’s Commercial-Off-The-Shelf (COTS) products are DO-254 certifiable, further emphasising its commitment to aerospace customers.
In addition, Holt offers product compliant to the European Union RoHS Directive 002/95/EC and is AS9100D:2016 and ISO 9001:2015 registered. Select products are also available to DSCC SMD specifications.
