Holt Pushes Rad-Hard MIL-STD-1553 Dual Transceiver to Higher SEE Limits

Enhanced Testing Confirms Greater Resilience in Harsh Space Environments with Holt 

Holt Integrated Circuits has announced that it has tested its recently released HI-1592  a radiation-hardened 3.3V MIL-STD-1553 dual transceiver designed for high-reliability and space applications for higher Single-Event Effects (SEE) levels. SEE levels encompass single-event transient (SET), single-event functional interrupt (SEFI), single-event latch-up (SEL) and single-event burnout (SEB), any of which can cause temporary or permanent damage to electronic components as a result of heavy ion or proton impact.

The HI-1592 is immune to latch-up and has been proven to withstand a single-event upset (SEU) with a Linear Energy Transfer (LET) of at least 86.3 MeV/cm²/mg, an improvement over the previous rating of 67.7 MeV/cm²/mg. Testing was carried out by Holt in collaboration with Zero-G Radiation Assurance at Texas A & M University, College Station, Texas. The device is radiation-tolerant to a total ionising dose (TID) of 100 krad(Si). This higher LET rating demonstrates enhanced robustness for use in launch vehicles, high-altitude aircraft, or space applications employing MIL-STD-1553 data bus communication.

Holt HI-1592 Key Features

The device also supports 1.8V, 2.5V and 3.3V compatible digital I/O, offering users greater flexibility to interface with a wide range of FPGAs and controllers without the need for level shifters or other additional circuitry. The HI-1592 is well-suited for use alongside Holt’s DO-254 certifiable MIL-STD-1553 IP Core, HI-6300, implemented in a radiation-hardened FPGA.

"Demonstrating higher SEE capability provides our customers with greater confidence in deploying Holt’s
rad-hard MIL-STD-1553 transceiver in demanding high-altitude and space environments"

Anthony Murray | Director of Marketing Communications at Holt Integrated Circuits

The HI-1592 is supplied in a hermetic 24-pin ceramic SOIC package and is available in an extended operating temperature range of -55°C to +125°C, with options for burn-in, 100% PIND testing, and compliance with MIL-PRF-38535 QML Class Q. Available from APC Technology Group’s high-reliability components team, Holt’s analogue and mixed-signal IC data bus solutions are designed to meet the rigorous demands of the avionics industry.
