Holt Tests Rad-Hard 1553 Dual Transceiver To Higher SEE Levels
August 5, 2025 - Aliso Viejo, CA – Holt Integrated Circuits today announced 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, to higher Single-Event Effects (SEE) levels. SEE levels collectively include single-event transient (SET), single-event functional interrupt (SEFI), single event latch-up (SEL) and single event burnout (SEB), causing temporary or permanent damage to electronic components as a result of heavy ion or proton impact.
The HI-1592 is latch-up immune and was proven to withstand a single-event upset (SEU) with a Linear Energy Transfer (LET) of at least 86.3 MeV-cm2/mg (previously tested to 67.7 MeV-cm2/ mg). Testing was performed by Holt in association with Zero-G Radiation Assurance at Texas A & M University, College Station, Texas. The device is radiation tolerant to a total ionizing dose (TID) of 100 krad(Si). The higher LET rating demonstrates additional robustness for use in launch vehicle, high-altitude aircraft or space applications utilizing MIL-STD-1553 data bus communication.
The device also features 1.8V, 2.5V and 3.3V compatible digital I/O. This feature gives users more flexibility to interface with a broad range of FPGAs and controllers, avoiding the use of level shifters and other additional circuitry. The HI-1592 is ideal for use with Holt’s DO-254 certifiable MIL-STD-1553 IP Core, HI-6300, instantiated in a radiation-hardened FPGA.
“Demonstrating higher SEE capability provides our customers with additional confidence to use Holt’s rad-hard MIL-STD-1553 transceiver in the demanding high-altitude and space environments,” said Anthony Murray, Director of Marketing Communications at Holt Integrated Circuits.
The HI-1592 is available in a hermetic 24-pin ceramic SOIC. The device is offered in an extended -55oC to +125oC temperature range, with the option of burn-in, 100% PIND testing and compliance with MIL-PRF-38535 QML class Q.
