IL 614

Overview

The IL 614 is a discontinued general-purpose digital isolator manufactured by NVE Corp/Isolation Products. It utilizes Giant Magnetoresistive (GMR) technology to provide electrical isolation without an isolated power supply. The device features three unidirectional channels with a data rate of 40Mbps and a common-mode transient immunity of 15kV/µs. It operates within a voltage range of 3V to 5.5V and supports a wide operating temperature range from -55°C to 125°C. The component is housed in a 16-SOIC package.

Feature Summary

• Utilizes Giant Magnetoresistive (GMR) spintronic technology for signal transmission
• Provides galvanic isolation without requiring an isolated power supply
• Features high common-mode transient immunity for noise rejection
• Supports operation across extended industrial temperature ranges

Applications

• General-purpose digital signal isolation in industrial systems
• Microcontroller interface isolation
• Data transmission path protection
• Noise reduction in sensitive measurement circuits

Procurement Notes

Verify the obsolete status of this part number before design finalization. Confirm that the specific GMR technology requirements align with system constraints. Evaluate the availability of the IL 614E as a potential alternative if functional equivalence is required. Ensure compliance with RoHS non-compliance status if applicable to the target market regulations.

Selection Notes

Select this component only if GMR technology offers specific advantages over capacitive or optical alternatives for the application. Consider the 16-SOIC package dimensions and pinout compatibility with existing PCB layouts. Assess the need for three unidirectional channels versus bidirectional options. Verify that the 40Mbps data rate meets the system's timing requirements.

Part Context

This component belongs to the IsoLoop® series from NVE Corp, which leverages spintronics for isolation. The IL 614 represents an earlier generation of GMR-based isolators. It is distinct from newer models like the IL 711T-2E which offer higher data rates. The series focuses on robust isolation performance without complex power management circuitry.

Replacement Considerations

The IL 614E is listed as a similar substitute by the manufacturer. Other manufacturers such as Broadcom offer equivalent digital isolators like the ACSL-6310-00TE. Verify pin compatibility and parameter margins when switching to these alternatives.
