IL 261-1E

Overview

The IL 261-1E is a general-purpose digital isolator from NVE Corp utilizing IsoLoop® technology. It features five channels with 2500Vrms isolation voltage and supports data rates up to 110Mbps. The device offers a common-mode transient immunity of 30kV/µs, with maximum propagation delays of 15ns for both low-to-high and high-to-low transitions. It operates on a single supply voltage ranging from 3V to 5.5V and is housed in a 16-SSOP package.

Feature Summary

• Utilizes patented IsoLoop® Giant Magnetoresistive (GMR) technology for signal transmission without optical or capacitive coupling elements.
• Provides robust common-mode transient immunity rated at 30kV/µs to maintain signal integrity in noisy environments.
• Features unidirectional channel configuration with an input distribution of four inputs on Side 1 and one input on Side 2.

Applications

• Isolating microcontroller interfaces in industrial automation systems
• Signal isolation in motor control drive circuits
• Protecting communication lines in power monitoring equipment

Procurement Notes

Verify the specific ordering suffix matches the required package type and tape/reel specifications. Confirm that the component meets RoHS3 compliance requirements for your assembly process. Ensure the selected variant aligns with the necessary isolation voltage ratings and operating temperature range for the target application environment.

Selection Notes

Select this component when high-speed digital isolation is required with superior noise immunity compared to traditional capacitive isolators. The GMR technology provides consistent performance across temperature variations. Consider the 16-SSOP footprint for space-constrained PCB layouts requiring five isolated channels.

Part Context

This part belongs to the IL261 series within NVE's IsoLoop® family of digital isolators. The series leverages giant magnetoresistive sensors and emitters to achieve galvanic isolation. The IL 261-1E specifically denotes the five-channel variant designed for general-purpose applications requiring reliable signal transfer across potential barriers.

Replacement Considerations

Direct functional substitutes may include other five-channel digital isolators with comparable isolation voltages and data rates. Verify pin compatibility and package dimensions before substitution. Check datasheets for equivalent CMTI ratings and propagation delay characteristics to ensure system stability.
