Digital Isolators

Digital isolators with iCoupler® technology enable designers to implement isolation in designs without the cost, size, power, performance, and reliability constraints found with optocouplers. With more than one billion channels shipped into the field, these magnetically isolated products are a safe, reliable and easy-to-use alternative to optocouplers.

Learn about the benefits of digital isolators, find safety and compliance information, use parametric search, and watch training videos and webcasts. Bookmark this page for your complete digital isolator resource.

 

Circuit from the lab Engineered. Tested. Ready to Integrate.
