Digital Isolator Product Selection
and Resource Guide
Spring 2014 Edition
Performance • Integration • Efficiency • Reliability • Safety
Digital isolators with iCoupler® technology enable designers to implement
isolation in designs without the cost, size, power, performance, and reliability constraints found with optocouplers. iCoupler digital isolators also meet
the wide range of creepage/clearance requirements and are the industry’s
only digital isolators with certified 8 mm creepage. With more than 1 billion
channels shipped into the field, these magnetically isolated products meet
the same rigid safety standards as optocouplers.
• Single and multichannel
data isolators
• Switching regulators
• Digital isolators with
isolated power: isoPower ®
• Isolated CAN transceivers
• Isolated gate drivers

Performance
4× improvement in data rate and timing specifications.
Integration
Multiple isolation channels integrated with other functions reduce
size, cost, and design complexity.
Power Consumption
Operates at power levels up to 90% lower than optocouplers.
Portfolio Offerings
• USB isolators
Advantages of the Broadest Portfolio of Digital Isolators
• I2C digital isolators
• Isolated RS-485 transceivers
• Isolated RS-232 transceivers
• Isolated Σ-∆ modulators
Ease of Use
Standard digital CMOS interfaces mean no external components
needed to connect to other digital devices.
Reliability
Eliminates LED wearout traditionally found in optocouplers.
Safety
Meets same rigid safety standards as optocouplers, including
reinforced insulation.
