Digital Isolators
Digital isolator ICs provide galvanic isolation between circuit domains using capacitive or magnetic coupling, replacing traditional optocouplers with higher speed, lower power, and better integration. Available from ADI (ADuM), TI (ISO), Silicon Labs (Si86), and STMicroelectronics.

Digital Isolator ICs are high-speed, physical-layer interface components designed to transmit digital logic signals across a galvanic isolation barrier while completely blocking high voltages, ground loops, and transient noise surges. Utilizing capacitive or magnetic (RF) coupling techniques, digital isolators represent a modern, high-performance replacement for traditional optocouplers, providing vastly superior data rates, lower power consumption, higher channel integration, and excellent long-term reliability.
Digital isolators protect sensitive microcontrollers in electric vehicle chargers, industrial motor drives, solar inverters, medical equipment, and high-voltage power supplies. Selection criteria depend on isolation voltage rating (measured in kV RMS), maximum data rate (Mbps), propagation delay, common-mode transient immunity (CMTI, measured in kV/microsecond), channel count and direction, and compliance with global safety standards (UL 1577, VDE, CSA). Many models integrate isolated DC-DC converters to supply power across the isolation barrier.
