IL 717-3B

Overview

The IL717-3B is a four-channel digital isolator from NVE’s IsoLoop series, offering a data rate of 110 Mbps. It features 2500 Vrms isolation voltage and operates within a temperature range of -40 °C to +125 °C. The device utilizes a 16-pin SOIC package with surface mount installation. Key electrical parameters include a propagation delay of 18 ns, rise time of 4 ns, and maximum input current of 10 μA. It supports a supply voltage up to 5.5V and complies with UL and IEC standards.

Feature Summary

• Patented IsoLoop technology provides high-speed signal transmission with low power consumption
• Offers robust galvanic isolation for noise immunity in harsh environments
• Supports wide operating temperature ranges suitable for industrial applications

Applications

• Industrial automation systems requiring isolated communication
• Medical equipment needing reinforced isolation barriers
• Power electronics control circuits

Procurement Notes

Verify the specific suffix (e.g., -3B) against official NVE documentation to ensure correct channel configuration and isolation ratings. Confirm package type and temperature grade match project requirements. Check for obsolescence status as distributors may list discontinued variants. Ensure compliance with relevant safety certifications for your application region.

Selection Notes

Select this component when high-speed digital isolation is required with low power consumption. Consider the 110 Mbps data rate and 2500 Vrms isolation level for general-purpose applications. Verify that the 16-pin SOIC package fits the PCB layout constraints. Compare against other IsoLoop variants if higher isolation voltages or different channel configurations are needed.

Part Context

The IL717-3B belongs to NVE’s IsoLoop family of digital isolators, which utilize magnetic coupling technology instead of optical or capacitive methods. This family is designed for applications demanding high reliability and long-term stability. The IL717 variant specifically offers four channels for parallel data transmission.

Replacement Considerations

Check NVE datasheets for direct replacements like IL717-3E or IL717-3T depending on temperature and isolation specifications. Verify pinout compatibility before substituting with other manufacturers' isolators.
