ALISO VIEJO, Calif. Holt Integrated Circuits announced it has tested its recently released\u00a0HI-1592, a radiation-hardened 3.3V\u00a0MIL-STD-1553 dual transceiver\u00a0designed for high reliability and space applications, to higher single-event effects (SEE) levels.<\/p>\n
SEE levels collectively include single-event transient (SET), single-event functional interrupt (SEFI), single event latch-up (SEL), and single event burnout (SEB) — all of these states can cause temporary or permanent damage to electronic components as a result of heavy ion or proton impact.\u00a0<\/p>\n
The HI-1592, say Holt officials, is immune to latch-up and was proven to during the tests 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). 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. Testing was performed by Holt in association with Zero-G Radiation Assurance at Texas A & M University.\u00a0<\/p>\n
\u201cDemonstrating higher SEE capability provides our customers with additional confidence to use Holt\u2019s rad-hard MIL-STD-1553 transceiver in the demanding high-altitude and space environments,\u201d said Anthony Murray, Director of Marketing Communications at Holt Integrated Circuits.<\/p>\n
The HI-1592 is available in a hermetic 24-pin ceramic SOIC. The device is offered in an extended -55\u00a0oC to +125\u00a0oC temperature range, with the option of burn-in, 100% PIND testing, and compliance with MIL-PRF-38535 QML class Q.<\/p>\n
