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.
| Holt P/N | Legacy P/N | Package |
| HI-15961PQx | HI-1596PQx | PQFP |
| BU-63152G3-902 | ||
| HI-15690PCTF* | BU-63155L3-102 | QFN |
| 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
