Holt Expands Autonomous ARINC 429 Receiver Family Operating with no MCU
4/9/2015

Holt Integrated Circuits today added two new devices to its novel ARINC 429 receiver family designed specifically for use without a microprocessor. All configuration and control is programmed using logic input pins, eliminating the need for a microprocessor or software interface and the related costs for software certification. The new devices provide an optional parity check feature, discarding words received with parity errors. Read more

Low Profile 3.3V MIL-STD-1553 Dual Transceiver with Integrated Transformers
3/11/2015

Holt Integrated Circuits today announced the introduction of a new 3.3V MIL-STD-1553/1760 dual transceiver with integrated dual transformers. At less than 4.6mm when mounted, this new device, HI-2579CG, has the lowest height and footprint available on the market today and is an ideal choice for applications using cards with component height restrictions, such as PMC and XMC.

Small Footprint, Cost Effective IC and Transformer Solutions for MIL-STD-1553 Applications
11/7/2014

Holt Integrated Circuits supplies the smallest footprint solutions for MIL-STD-1553 applications available on the market today. All protocol ICs integrate dual analog transceivers on-chip and operate from a single 3.3V supply. Select products communicate with the host using a 4-wire Serial Peripheral Interface (SPI), further reducing pin-count and size. When paired with Holt’s MIL-STD-1553 transformers, the resulting combination results in a compact, highly robust solution. Read more

New 3.3V MIL-STD-1553 Dual Transceiver with Digitally Programmable Transmit Amplitude
10/29/2014

Holt Integrated Circuits today introduced HI-1590, a new MIL-STD-1553 dual-bus transceiver with variable amplitude transmitter outputs. The output amplitude is controlled by programming an internal Digital-to-Analog Converter (DAC) via a Serial Peripheral Interface (SPI) or using an analog control voltage input. The new device is pin-compatible with Holt’s already popular HI-1570 and is designed for use with Holt MIL-STD-1553 isolation transformers. Read more

New Discrete-to-Digital Sensor with Programmable Sense Thresholds and Internal Lightning Protection
10/21/2014

Holt Integrated Circuits today announced a new discrete-to-digital sensor IC, HI-8429, an 8-channel device with programmable sense channels and internal lightning protection. The sense input thresholds are programmable via a 10MHz SPI bus and each channel may be individually configured as GND/Open or Supply/Open (28V/Open) sensors. Additional features include an optional debounce circuit and sensor output interrupt pin. Read more

Development Kits for Latest Aircraft Discrete-to-Digital Parts
9/18/2014

Holt Integrated Circuits announced today two new development kits for its latest discrete-to-digital sensor ICs. The ADK-8428 and ADK-8428-R kits demonstrate the features of HI-8428 and HI-8428-R, octal discrete sensing devices with individually configurable channels and SPI interface. The boards contain a 16-bit Freescale MCU and software which demonstrate a typical 4-wire SPI interface to an avionics discrete-to-digital IC. Read more
