IL 610A-2E

Overview

The IL610A-2E is a single-channel passive-input digital isolator from the NVE IL600A series. It utilizes Giant Magnetoresistive (GMR) technology to provide galvanic isolation with CMOS outputs. The device supports a supply voltage range of 3V to 5.5V and operates within an industrial temperature range of -40°C to 85°C. Key electrical characteristics include a typical rise/fall time of 2ns, a data rate capability up to 100Mbps, and a common-mode transient immunity of 15kV/µs. It is housed in an 8-DIP package.

Feature Summary

• Passive input design requiring no external pull-up resistors for operation
• Open-drain output configuration providing flexible interfacing capabilities
• Failsafe output mechanism ensuring logic high state during zero input conditions

Applications

• General-purpose digital signal isolation in industrial control systems
• Isolating microcontroller interfaces from noisy peripheral circuits
• Protecting low-voltage logic inputs from high-voltage transients

Procurement Notes

Verify the specific suffix '2E' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure the operating environment remains within the specified -40°C to 85°C range. Confirm that the open-drain output requirement aligns with the destination circuit's input impedance and pull-up resistor availability before finalizing procurement.

Selection Notes

Select this component when a passive input interface is required to simplify circuit design by eliminating external pull-up components. The open-drain output is suitable for level shifting applications between different voltage domains. Consider the 15kV/µs CMTI rating for environments with rapid voltage transitions. Verify that the 8-DIP package fits the available PCB footprint constraints.

Part Context

This part belongs to the NVE IL600A series of GMR-based digital isolators. Unlike traditional optical or capacitive isolators, it offers higher package density and superior performance metrics. The series includes variants with different channel counts and output types, but the IL610A-2E specifically provides a single channel with open-drain output characteristics.

Replacement Considerations

Direct replacements must match the 8-DIP package and single-channel configuration. Verify that any substitute maintains the passive input requirement and open-drain output type. Check that the replacement device meets or exceeds the 15kV/µs common-mode transient immunity specification for equivalent noise rejection performance.
