ISL71610-710EV1Z

The ISL71610-710EV1Z evaluation board features the ISL71610M and ISL71710M radiation tolerant digital isolators or ISL71710SLHM rad hard Giant Magnetoresistive (GMR) digital isolator parts. These ICs are radiation tolerant digital isolators designed for isolated power supply designs and isolated serial communications interfaces, such as CAN, SPI, RS-422, and RS-485 applications.

The ISL71610M is a passive input, active output GMR digital isolator that requires a 3V to 5.5V supply to power its CMOS output. The ISL71710M is an active input, active output GMR digital signal isolator that requires an input and output supply voltage in the range of 3V to 5.5V. The ISL71710M can be used to level shift the digital signal at its input.

These GMR isolators can replace some of the available optocouplers currently used in space applications. Whereas optocoupler lines are susceptible to Total Ionizing Dose (TID) radiation that causes the optics to become cloudy, thus compromising the signal, the GMR inductive structure used in the ISL71610M and ISL717170M is inherently immune to radiation effects.
