Holt releases drop-in replacements for legacy MIL-STD-1553 transceivers

Holt Integrated Circuits announce two new MIL-STD-1553A transceiver families, suitable for flight control and monitoring, and stores management.

Holt Integrated Circuits recently announced the release of two MIL-STD-1553 transceiver families, HI-15690 and HI-15691, which provide pin-compatible, “form, fit and function” drop-in replacements for legacy Holt and other manufacturer’s devices, summarised in the table below. These devices may also be paired with the recommended Holt MIL-STD-1553 transformers.

HI-15690CDx BUS-63105 Ceramic DIP
BUS-63107 Ceramic DIP

*Compatible with both leaded and lead-free assemblies

The HI-15690 family is a 5V, single-channel MIL-STD-1553 transceiver, whereas the HI-15691 family is a dual-channel version. All devices guarantee a minimum transformer-coupled output voltage of 20Vp-p, making them also suitable for MIL-STD-1760 applications, such as flight control and monitoring or stores management.

Holt's HI-15690 and HI-15961 are low power CMOS transceivers designed to meet the requirements of the MIL-STD-1553 and MIL-STD-1760 specifications. The HI-15960 is also available as a small footprint 7mm x 7mm plastic QFN package with an integral heatsink.

  • Compliant to MIL-STD-1553A and B, MIL-STD-1760 and ARINC 708A
  • Single +5.0V power supply
  • Industrial and extended temperature ranges available
  • Drop-in alternative for Data Device Corporation BU-63155L3 (QFN) and BUS-63105 / BUS-63106 (ceramic DIP) transceivers
"Product obsolescence is a major concern for our customers, incurring significant cost for re-design and qualification, the availability of second source 'form, fit and function' drop-in replacements gives our customers the option to mitigate these costs."
