Digital Isolators Market 2018 by Manufactures(Silicon Labs, ADI, TI, Broadcom Corporation, Maxim Integrated, Vicor) - Global Forecast to 2023

They serve a similar purpose to optocouplers, except optocouplers are far too slow and error prone for high speed (1MHz+) digital signals. They also use a different coupling technology, usually transformer or RF link as opposed to an optical link.
