The HI-1592 is a radiation-hardened, hermetically packaged MIL-STD-1553 dual transceiver designed for use in high reliability MIL-STD-1553 applications, such as launch vehicles, high altitude aircraft and space. As aircraft fly at higher altitudes or in space they become more susceptible to exposure to cosmic rays, resulting in effects such as single-event transient (SET), single-event functional interrupt (SEFI), single event latch-up (SEL) and single event burnout (SEB), any of which could result in degradation or failure of electronic equipment. To that end, electronic equipment designed to fly in these environments needs some level of latch-up immunity or radiation hardness assurance (RHA) against the effects of cosmic rays.
