Holt Integrated Circuits announced the introduction of HI-8470, a 16-channel discrete-to-digital sensor with built-in ARINC 429 transmitter. All sense input thresholds and ARINC 429 transmission control are programmed via logic level input pins, eliminating the need for a microprocessor or software interface.

Holt Integrated Circuits today announced formal MIL-STD-1553 RT validation of HI-6130/31, the world’s smallest BC/MT/RT multi-terminal solution. Validation was performed at Test Systems, Inc., an independent Air Force approved testing service for MIL-STD-1553 remote terminals. A validation report is available on request.

Holt Integrated Circuits today announced the availability of evaluation boards for its latest discrete-to-digital product line. Three different boards are available to demonstrate the unique features of HI-8425, HI-8430 and HI-8435 product families.

Holt Integrated Circuits today announced the introduction of HI-8435, a new 3.3V, 32-channel, discrete-to-digital sensing IC with SPI interface and built-in lightning protection.

Holt Integrated Circuits today announced compliance of its flagship 3.3V ARINC 429 line driver, HI-8597, with the lightning requirements of RTCA/DO-160G, Section 22, Level 3 Pin Injection Test, using no additional external components. The integrated lightning protection brings the highest level of robustness to all applications even if lightning stress is not a concern.

Holt Integrated Circuits today announced the introduction of a family of CAN transceivers capable of operating in temperatures from −55°C to 200°C. The devices are ARINC 825 / ISO 11898-5 compliant and are targeted at high temperature avionics and industrial applications such as aircraft braking systems, engine controls and down-hole drilling.

Holt Integrated Circuits today announced the introduction of HI-8425, a new 3.3V octal discrete-to-digital sensing IC with quad low-side drivers and built-in lightning protection. The device is also fully compliant to Airbus ABD0100H.

Holt Integrated Circuits, a world leader in data bus IC’s for the avionics and military industries, today introduced the world’s first ARINC 429 line driver capable of meeting DO-160G Level 3 pin injection waveforms without external components. The HI-8597 operates from a single 3.3V power supply, eliminating the higher voltage supplies needed with other ARINC 429 line drivers.

Holt Integrated Circuits today announced the introduction of a family of RS-485/422 transceivers capable of operating in temperatures from −55°C to 200°C. The HI-4853H family is capable of data rates up to 20Mbps

Holt Integrated Circuits today expanded its Analog Switch family with the release of three new products capable of switching analog signals outside the range of IC rail voltage. The devices can switch +/− 12V signals while operating from a supply range of 3.0V to 5.5V.
