Holt’s range of avionics products has served the aerospace industry for many years. Many of Holt’s data bus product lines integrate analog transceiver and digital protocol functions in a single integrated circuit, resulting in significant space savings and improved reliability.
Holt introduced its first ARINC 429 ICs in 1990 in response to many requests from avionics manufacturers for an alternate, cost effective source of monolithic devices for this protocol.
Holt MIL-STD-1553 solutions are the smallest and most cost effective in the industry, providing the entire 1553 interface on a single chip.
Controller Area Network (CAN) devices have become a popular data bus solution in the avionics industry, most notably since the release of the ARINC 825 specification in November 2007, which standardized the use of CAN in avionics applications.
Holt is the first company to provide an ARINC 717 solution in a single chip, including integrated line drivers and receivers and on-chip DC/DC converter for 3.3V single supply operation.
Holt's range of rugged RS-485/422 transceivers is ideal for avionics applications such as Time Triggered Protocol (TTP) and Miniature Munitions Store Interface (MMSI / EBR-1553). High operating temperature products (up to 200C) are also available.
Holt’s range of Discrete-to-Digital components provides a robust solution for sensing Open / Ground and 28V / Open discrete signals.
Holt's Analog switch product line is specifically designed for use in harsh environments such as avionics. The robust SOI technology makes these devices ideal for applications that benefit from or require low charge injection, high isolation or low leakage.
Holt Integrated Circuits' line of LCD Display Drivers is designed for high voltage LCD display drive applications.
