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.
The IP core is based on Holt’s independently validated monolithic protocol ICs for MIL-STD-1553, namely Holt’s HI-6130 and MAMBATM families, and is fully software compatible with them.
The core supports Bus Controller (BC), Monitor Terminal (MT) and Remote Terminal (RT) functions, with all options having a high-performance synchronous host interface allowing easy connection to AMBA AXI4 interface protocol or PCI-Express. Enabled terminals communicate with the MIL-STD-1553 buses through a shared dual bus transceiver, HI-1587, and external isolation transformer, also available from Holt. The HI-1587 is the world’s first MIL-STD-1553 transceiver featuring 1.8V, 2.5V and 3.3V compatible digital I/O and includes an integrated IP security module eliminating the need for a separate dongle chip to unlock the IP.
| Holt P/N | Legacy P/N | Package |
| HI-15961PQx | HI-1596PQx | PQFP |
| HI-15961PQx | BU-63152G3-902 | PQFP |
| HI-15690PCTF* | BU-63155L3-102 | QFN |
| HI-15690CDx | BUS-63105 | Ceramic DIP |
| HI-15690CDx | 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.”
