Digital Isolators

ICs for signal isolation in communication and control systems

Digital isolators protect sensitive components by separating high-voltage and low-voltage sides of a circuit while allowing digital signals to pass through. A digital isolator IC is used in motor controls, power supplies, and data interfaces to prevent noise, ground loops, or surges from damaging equipment. These ICs provide fast, reliable signal transfer without the drawbacks of optocouplers. Use Octopart to quickly find the digital isolator or other interface ICs you need. Then you can compare suppliers, view datasheets, and check real-time pricing and availability.
