IL 261-3

Digital Isolators Overview

The IL 261-3 is a general-purpose digital isolator from the IsoLoop® series, utilizing Giant Magnetoresistive (GMR) technology. It provides 2500Vrms isolation across five channels with a data rate of 110Mbps and a common-mode transient immunity of 30kV/µs. The device operates on a 3V to 5.5V supply, features unidirectional channel types with a 4-input/1-output configuration, and supports propagation delays up to 15ns. It is housed in a 16-SOIC package and functions within a temperature range of -55°C to 125°C.

Digital Isolators Procurement Notes

Verify component authenticity through authorized distributors as the IL 261-3 may be discontinued or superseded by variants like the IL 261-3E. Confirm RoHS compliance status and specific package markings against official datasheets before integration. Ensure supply chain stability due to potential obsolescence of this specific part number.

Digital Isolators Selection Notes

Select the IL 261-3 for applications demanding high CMTI and wide operating temperature ranges. Compare against the IL 261-1E for different pinout configurations or the IL 712-3 for lower channel counts. Validate that the 4/1 input/output split aligns with system architecture requirements.

Digital Isolators Part Context

Part of the NVE IsoLoop family using spintronics. Replaced or supplemented by IL 261-3E and IL 261-1E. Competes with silicon-based isolators offering similar voltage ratings but different isolation mechanisms.

Digital Isolators Replacement Considerations

IL 261-3E is a confirmed substitute variant. Verify pin compatibility and RoHS status differences between the original IL 261-3 and the E-suffix version.
