Shadin Avionics Uses Holt’s MIL-STD-1553 Terminal IC Solution in TSO Certified Avionics Interface System

Thursday, September 26, 2013

Mission Viejo, CA (September 26, 2013) – Holt Integrated Circuits today announced that Shadin Avionics selected its MIL-STD-1553 BC/MT/RT terminal IC, HI-6131PCTF, and stacked dual core isolation transformer, PM-DB2762, for use in their TSO Certified Avionics Interface System, AIS-460. Shadin Avionics AIS-460 converts MIL-STD-1553 to ARINC 429 and other avionics signals.

“Holt is delighted Shadin selected our 1553 terminal IC for such a key product,” said David Mead, President and CEO of Holt. “Our small footprint, 4-wire SPI interface and low power consumption make this product a perfect fit for Shadin’s application.”

Holt’s HI-6131PCTF terminal IC integrates logic, memory and analog transceivers to result in the world’s smallest, complete 3.3V BC/MT/RT solution. Key features include concurrent operation for up to four terminals (Bus Controller, Monitor Terminal and one or two Remote Terminals), 64K bytes of internal static RAM with optional error detection/correction, a fully programmable Bus Controller and serial peripheral host interface (SPI). The compact SPI interface was one of the primary factors in Shadin Avionics selection criteria. The enabled terminals communicate with the MIL-STD-1553 buses through the on-chip dual transceiver and external dual transformer, PM-DB2762, also supplied by Holt.

“We offer data conversion units at a fraction of the cost and time as compared to typical development programs,” commented Shadin’s CEO, Dan Nelson. “Holt’s highly integrated ICs are easy to use and ultimately save us money in terms of board space and software development.”

Holt offers a complete portfolio of ARINC 429 and MIL-STD-1553 ICs, providing a solution for all application needs and configurations. All products are DO-254 certifiable, providing customers a more efficient and cost effective path to certification.
