IL 717VE

Overview

The IL717VE is a general-purpose digital isolator from the IsoLoop series, manufactured by NVE Corp/Isolation Products. It features four independent channels with a maximum data rate of 110 Mbps and a common-mode transient immunity (CMTI) of 100 kV/µs. The device provides an isolation voltage of 6000 Vrms and operates within a supply voltage range of 3 V to 5.5 V. It utilizes Giant Magnetoresistive (GMR) technology for signal transmission without an isolated power supply. The component is housed in a 16-SOIC package with a width of 7.50 mm and supports surface-mount installation across an operating temperature range of -40°C to 125°C.

Feature Summary

• Utilizes GMR technology for high-speed digital signal isolation without requiring an isolated power supply
• Provides robust 6000 Vrms isolation voltage capability for demanding applications
• Delivers high common-mode transient immunity of 100 kV/µs to maintain signal integrity in noisy environments

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-voltage safety isolation
• Power electronics control circuits

Procurement Notes

Verify the specific suffix 'VE' to confirm the 6000 Vrms isolation rating, as other variants like IL717E offer lower ratings. Ensure the 16-SOIC package dimensions match the PCB footprint requirements. Confirm RoHS compliance status if required by project specifications. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when high isolation voltage (6000 Vrms) is critical compared to standard 2500 Vrms options. The 110 Mbps data rate suits high-speed communication interfaces. Consider the 16-pin SOIC package size constraints against available board space. Verify that the unidirectional channel configuration meets the system's signal flow requirements.

Part Context

The IL717VE belongs to NVE's IsoLoop family, which leverages giant magnetoresistive sensors for isolation. This technology distinguishes it from capacitive or optical isolators by eliminating the need for on-chip isolated power supplies. The VE suffix specifically denotes the enhanced 6000 Vrms insulation level within the IL717 product line.

Replacement Considerations

IL717TE: Offers similar functionality but with a lower 2500 Vrms isolation rating. IL717VE-ND: Standard distributor packaging variant.
