Holt Announces Radiation-Hardened 3.3V MIL-STD-1553 Dual Transceiver for High Reliability and Space Applications

HOLT expands its MIL-STD-1553 portfolio with their first Radiation Hardened MIL-STD-1553 Dual Transceiver for Hi-Rel applications such as launch vehicles and high-altitude aircraft.

Holt Integrated Circuits has announced the introduction of HI-1592, a radiation-hardened 3.3V MIL-STD-1553 dual transceiver for high reliability and space applications.

Holt has been a supplier of MIL-STD-1553 IP, protocol, transceiver and transformer components to the military and aerospace industries for over 20 years and this new product offering provides additional robustness for demanding Hi-Rel applications such as launch vehicles, high-altitude aircraft, low-orbit satellites, 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 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.

The HI-1592 is latch-up immune and proven to meet a single-event upset (SEU) with an LET of at least 67.7 MeV-cm2/mg. The device is radiation tolerant to a total ionizing dose (TID) of 100 krad(Si).

It is ideal for launch vehicle and high-altitude aircraft applications utilising 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.
