Digital Isolator Product Selection

and Resource Guide

Performance  • Integration •  Efficiency  • Reliability • Safety

Digital isolators with iCoupler® technology enable designers to implement

isolation in designs without the cost, size, power, performance, and reliabil-

ity 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 half a

billion channels shipped into the field, these magnetically isolated products

meet the same rigid safety standards as optocouplers.

Portfolio Offerings

• Single and multichannel

data isolators

• Digital isolators with

isolated power: isoPower®

• USB isolators

• Isolated gate drivers

• I2C® digital isolators

• Isolated CAN transceivers

• Isolated RS-485 transceivers

• Isolated RS-232 transceivers

• Isolated Σ-∆ modulators

Advantages of the Broadest Portfolio of Digital Isolators

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.

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.
