Renesas' radiation hardened digital isolators are designed for isolated power supply designs and isolated serial communications interfaces, such as CAN, SPI, RS-422, and RS-485 applications. These rad hard isolators offer isolation function for the space market, providing up to 600VRMS at 85 °C. The electrical specifications have been characterized over the temperature range of -55 °C to +125 °C. And, these products have been characterized for radiation performance up to 75krad(Si) for Total Ionizing Dose (TID). The ISL71610SHM and ISL71710SLHM have both been characterized for Singe Event Effects (SEE) up to LET 86MeV•cm2/mg.
