IL 716-3B

Overview

The IL716-3B is a high-speed digital isolator from the NVE IL series, featuring four independent channels within a 16-pin SOIC package. It supports data rates up to 110 Mbps with a propagation delay of approximately 18 ns and rise times around 4 ns. The device operates on a supply voltage range of 3V to 5.5V and maintains functionality across an extended temperature range of -40°C to +125°C. Key electrical specifications include a maximum input current of 10 μA and a common-mode transient immunity of 100 kV/μs. The component provides reinforced isolation capabilities rated at 7 kVRMS for the V-series variants.

Feature Summary

• Provides galvanic isolation between circuits using magnetic coupling technology
• Supports high-speed digital signal transmission up to 110 Mbps
• Operates reliably in extreme thermal environments up to 125°C
• Features low power consumption with minimal input drive requirements

Applications

• Industrial automation control systems requiring robust signal isolation
• Medical equipment interfaces needing reinforced safety barriers
• Power electronics monitoring and gate driving applications
• Data acquisition systems with mixed-signal ground separation

Procurement Notes

Verify the specific suffix designation (e.g., -3B) against official NVE documentation to confirm exact isolation ratings and pinout configurations. Ensure the selected variant meets the required insulation standards for your application's safety regulations. Cross-reference datasheet parameters such as CMTI and operating temperature ranges before finalizing procurement decisions.

Selection Notes

Select this component when high channel density and wide operating temperature ranges are critical. Compare the IL716-3B against other IL series parts based on required channel count and isolation voltage levels. Consider the 16-pin SOIC footprint constraints and verify compatibility with existing PCB layouts. Evaluate the 110 Mbps speed requirement against system timing budgets.

Part Context

The IL716-3B belongs to the NVE IL family of digital isolators, which utilize proprietary magnetic sensor technology rather than traditional optical or capacitive methods. This family is designed for applications demanding high reliability and long-term stability. The IL716 variant specifically offers four channels, providing a compact solution for multi-channel isolation needs compared to single-channel alternatives.

Replacement Considerations

Consult official NVE substitution guides for verified equivalents. Generic replacements may not match the specific magnetic coupling characteristics or isolation ratings. Verify that any substitute part maintains the same pinout and electrical performance metrics.
