Holt Integrated Circuits today announced that Gables Engineering selected its HI-8444 Quad ARINC 429 Line Receiver and HI-8596 3.3V Single-Rail ARINC 429 Line Driver for use in the new Gables gTools ARINC Bus Analyzer.

Holt Integrated Circuits today introduced a new Application Programming Interface (API) for its MIL-STD-1553 integrated terminal devices, HI-6130 and HI-2130. The API applies a standardized set of functions for configuration, control, status, and interrupt processing, isolating the programmer from low-level register, RAM and discrete I/O transactions operating in the background.

Holt Integrated Circuits today introduced several application development kits to complement its recently introduced family of autonomous ARINC 429 devices, HI-8470, HI-8475 and HI-8476. These devices connect directly to the ARINC 429 bus and enable transmission or reception of data without using an MCU or software. All control and configuration is done in hardware, by strapping logic-level input pins.

Holt introduces a new ARINC 429 line receiver family with fully integrated lightning protection circuitry. The built-in circuitry ensures compliance with RTCA/DO-160G, Section 22 Level 3 Pin Injection Test Waveform Set A (3 & 4), Set B (3 & 5A) and Set Z (3 & 5B), enabling direct connection to the ARINC 429 bus without external components. All devices operate from a 3.3V or 5.0V supply.

Contrary to what one may assume, a repeater is more than simply connecting the output of an ARINC 429 line receiver to the input of a line driver. Such simple solutions usually result in transmitted waveforms that violate ARINC 429 timing requirements. Holt provides an elegant and cost effective solution for an autonomous ARINC 429 repeater using a two-component solution, eliminating microcontroller, software and associated certification costs, and any additional ARINC 429 protocol devices.

Holt Integrated Circuits expands its discrete-to-digital portfolio with the introduction of HI-8437, a 3.3V, 32-channel, discrete-to-digital sensing IC with SPI interface and low threshold sensing capability. The high impedance sense input thresholds and hysteresis are programmable via the 20MHz SPI port in 100mV steps, from 0.4V to 5.2V and all 32 sense output states may be read with a single SPI command. In addition, the device has built-in lightning protection on the sense inputs.

Holt Integrated Circuits today announced the introduction of HI-1582, a pin-compatible, “form and fit” drop-in replacement for the Data Device Corporation MIL-STD-1553 transceiver, BU-63133L8. The new device is a single-channel transceiver designed for use with Holt MIL-STD-1553 isolation transformers with 1:2.50 turns ratio.

Holt Integrated Circuits announced the introduction of HI-8475, a novel ARINC 429 receiver 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.

Holt Integrated Circuits today announced an extended temperature version of the popular HI-15530, a MIL-STD-1553 encoder/decoder used extensively on legacy military platforms and down-hole drilling applications. The device can operate in the temperature range -55°C to +200°C and is also a drop-in replacement for the Intersil HD-15530.

Holt Integrated Circuits was presented with the 2012 Gold Supplier Award by Stack International, a consortium of leading defense and aerospace OEMs committed to component evaluation and source certification. Stack International is comprised of member companies Lockheed Martin, Honeywell International, GE Aviation Systems, Rockwell Collins, Northrop Grumman, United Technologies, Crane Aerospace, Plexus Corporation, Meggitt AB Systems and Aero Engine Controls.
