Digital Isolator Product Selection and Resource Guide

Product catalog summary

Overview
Digital isolators with iCoupler® technology offer a solution for implementing isolation in designs without the typical constraints of optocouplers. These isolators meet various creepage/clearance requirements and are the only digital isolators with certified 8 mm creepage. Over half a billion channels have been shipped, adhering to the same safety standards as optocouplers.

Portfolio Offerings

Single and multichannel data isolators
Digital isolators with isolated power (isoPower®)
USB isolators
