IL 611A-2

Overview

The IL 611A-2 is a general-purpose digital isolator from the IsoLoop series, utilizing Giant Magnetoresistance (GMR) technology. It features two independent channels with a unidirectional input-to-output configuration (2/0). The device provides 2500Vrms isolation voltage and supports data rates up to 10Mbps. It operates within a supply voltage range of 3V to 5.5V and functions across an industrial temperature range of -40°C to 85°C. The component is housed in an 8-PDIP package.

Feature Summary

• Employs GMR sensor technology for galvanic isolation without requiring isolated power supplies
• Provides high common-mode transient immunity of 15kV/µs for reliable signal transmission
• Features unidirectional channel architecture suitable for standard logic interface applications

Applications

• Industrial process control systems requiring signal isolation
• Medical equipment needing safe patient isolation barriers
• General-purpose digital communication interfaces

Procurement Notes

Verify the specific package type against design requirements, as the IL 611A suffix typically denotes the 8-PDIP variant distinct from TSSOP or SOIC versions. Confirm RoHS compliance status and ensure the ordering part number matches the exact pinout and isolation specifications required for the target application circuit.

Selection Notes

Select this component when a robust, non-optical isolation solution is needed for bidirectional or unidirectional data links. The GMR technology offers superior longevity compared to optical isolators. Ensure the system voltage aligns with the 3V to 5.5V operating range and that the 2500Vrms isolation rating meets safety standards.

Part Context

This device belongs to the IL600A series of digital isolators manufactured by NVE Corp. The series leverages proprietary GMR technology to replace traditional optocouplers. The IL 611A-2 specifically refers to the dual-channel version in the PDIP package format, offering a direct replacement path for legacy DIP-based isolation designs.

Replacement Considerations

HCPL-0930 is documented as a similar substitute option.
