Holt Inc releases Drop-In Replacements for DDC® MIL-STD 1553

Holt Inc has introduced several new families of MIL-STD 1553 terminals, available in the UK from APC Hi-Rel, offering direct drop-in replacements for DDC® MIL-STD 1553.

APC Technology Group plc

Holt’s new product families of MIL-STD 1553 terminals offer both pin and software register level compatibility with many Data Device Corporation (DDC®) MIL-STD 1553 terminals.  All families provide complete form, fit and functional replacements allowing users to drop-in to existing 1553 designs with no changes required to the existing board layout or software.

The single-chip monolithic design allows Holt to offer reduced cost and lower lead times over the older traditional hybrid or multi-chip module approach. The higher maximum junction temperature of the Holt devices supports extended temperature (-55°C to +125°C) operation with no limitations on transmit duty cycle or special heat sinking required.

“These new drop-in devices offer users the option to realize significant cost savings, reduced lead-times, and potential obsolescence mitigation when compared to existing hybrid or multi-chip module solutions” said Sean Sleicher, Director of Business Development for Holt Integrated Circuits.“Given the cost of re-design and qualification, providing our customers with an equivalent, reliable, and cost effective second source just makes sense”.

Fully register-level software compatible and fully pin compatible with the DDC®:

  • Mini-ACE®,
  • Enhanced Mini-ACE®,
  • Micro-ACE® TE,
  • Micro-ACE
  • Mini-ACE® Mark3,
  • Total-ACE®
  • and Simple System RT (SSRT) families of MIL-STD-1553 terminals.
