Holt’s founder, entrepreneur William G. Holt, has published a new memoir, “Engineering Your Career and Life: Lessons Learned While Building a Technology Business”.

Holt Integrated Circuits today announced it has tested its recently released HI-1592, a radiation-hardened 3.3V MIL-STD-1553 dual transceiver designed for high reliability and space applications, to higher Single-Event Effects (SEE) levels. The device is latch-up immune and was proven to withstand a single-event upset (SEU) with a Linear Energy Transfer (LET) of at least 86.3 MeV-cm2/mg and is radiation tolerant to a total ionizing dose (TID) of 100 krad(Si).

Holt announced its entry into the Space Market at Aero India 2025, unveiling its recently released radiation-hardened MIL-STD-1553 transceiver.

Holt Integrated Circuits announced today it will exhibit at the Aero India 2025 show, held between February 10 – 14, at the Yelahanka Air Force Station in Bangalore, India. Aero India is the largest air show and aviation exhibition in Asia, organized by India’s Ministry of Defence.

Holt Integrated Circuits today announced the introduction of ADK-1592, a development kit designed to help customers interface Holt’s recently announced HI-1592 rad-hard transceiver with a MIL-STD-1553 protocol controller or FPGA. The HI-1592 is latch-up immune and proven to withstand a single-event upset (SEU) with an LET of at least 67.7 MeV-cm2/mg. It is radiation tolerant to a total ionizing dose (TID) of 100 krad(Si) and is ideal for launch vehicle, high-altitude aircraft and low orbit satellite applications utilizing MIL-STD-1553 data bus communication.

Holt Integrated Circuits today announced the introduction of ADK-84216, a development kit designed to demonstrate the features of Holt’s recently announced programmable 16-channel low side driver, HI-84216. This device was designed to drive a wide variety of loads, such as LED dimmers, relays, solenoids, valves, actuators, small DC motors and incandescent lamps operating in high reliability aerospace and defense environments.

Holt Integrated Circuits today announced the introduction of HI-84216, a smart 16-channel low-side driver designed for high reliability avionics applications. The device uses a Serial Peripheral Interface (SPI) for intelligent switch control, monitoring and advanced diagnostics. It is capable of sinking 250mA per channel with up to 4A total sink current for parallel channel operation.

Holt Integrated Circuits today announced the introduction of HI-1592, a radiation-hardened 3.3V MIL-STD-1553 dual transceiver for high reliability and space applications. This new product offering provides additional robustness for demanding Hi-Rel applications such as launch vehicles, high-altitude aircraft, low-orbit satellites, and space.

Holt Integrated Circuits today announced the completion of the transition from its Mission Viejo location to a new 38,000 sq. ft. facility in Aliso Viejo, California, which is the culmination of a $12.6 million facility investment in 2022.

Holt Integrated Circuits today announced an expansion of its family of legacy drop-in replacement MIL-STD-1553 Terminals to include the DDC® Mini-ACE® and Mini-ACE Plus® families. All drop-in families are both pin and software register level compatible.
