IL611E

Digital Isolators Overview

The IL611E is a general-purpose digital isolator from the IsoLoop series, utilizing Giant Magnetoresistive (GMR) technology. It provides 2500Vrms isolation voltage with a data rate of 10Mbps and a minimum Common Mode Transient Immunity (CMTI) of 15kV/µs. The device features two unidirectional channels with a supply voltage range of 3V to 5.5V. Operating temperatures span from -40°C to 85°C. Propagation delays are specified at maximum 75ns for low-to-high and 25ns for high-to-low transitions.

Digital Isolators Feature Summary

• Employs GMR sensing technology for robust signal transmission across isolation barriers
• Provides high common mode transient immunity to withstand rapid voltage changes
• Offers galvanic isolation without requiring isolated power supplies

Digital Isolators Applications

• General purpose digital signal isolation in industrial systems
• Microcontroller interface protection in noisy environments
• Isolation for communication buses requiring moderate data rates

Digital Isolators Procurement Notes

Verify the specific package variant required, as the base model number may correspond to different physical footprints such as TSSOP or SOIC depending on the suffix. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications before ordering. Ensure the selected variant matches the intended board layout constraints.

Digital Isolators Selection Notes

Select this component when GMR-based isolation offers advantages over capacitive or optical alternatives regarding size and reliability. Consider the 10Mbps data rate limit and 2500Vrms isolation rating against system requirements. Evaluate the 3V to 5.5V supply range compatibility with the target logic levels. Check if the specific channel configuration meets the bidirectional or unidirectional needs of the application.
