IL 711T-3E

Overview

The IL711T-3E is a dual-channel digital isolator manufactured by NVE using IsoLoop spintronic technology. It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 110 Mbps. The device provides 2500 Vrms isolation capability with a typical common-mode transient immunity of 100 kV/µs. It features a propagation delay of 10 ns and pulse width distortion of 2 ns. The component is housed in an 8-SOIC surface-mount package and functions reliably across an industrial temperature range of -40°C to +125°C.

Feature Summary

• Utilizes patented IsoLoop spintronic technology for high-speed signal transmission
• Provides robust galvanic isolation between input and output channels
• Offers high common-mode transient immunity for noise-resistant operation
• Supports CMOS logic levels compatible with 3.3V and 5V systems

Applications

• Isolated data transmission interfaces
• Fieldbus isolation circuits
• High-speed digital system interconnects
• Logic level shifting applications

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation matches NVE Corp or authorized Isolation Products divisions. Ensure the datasheet version aligns with the 110 Mbps speed rating and 100 kV/µs CMTI specifications. Cross-reference the 8-SOIC footprint dimensions against your PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component for designs requiring high-speed bidirectional or unidirectional isolation with low power consumption. The 110 Mbps rate suits most standard communication protocols. Verify that the 2500 Vrms isolation rating meets the safety standards of your target application environment. Consider the SOIC package size constraints relative to available board space and thermal management needs.

Part Context

This part belongs to the IL711 family of digital isolators from NVE. The family utilizes unique spintronic sensors rather than traditional optical or capacitive methods. This architecture enables superior performance in terms of speed, power efficiency, and reliability compared to conventional isolation technologies. The T-3E suffix typically denotes specific packaging and compliance attributes within the product line.

Replacement Considerations

Direct replacements include other variants within the IL711 series such as IL711-3E or IL711S-1E, depending on required package type (SOIC vs MSOP). Verify pinout compatibility and electrical parameters like propagation delay and isolation voltage before substituting. Ensure any alternative maintains the same operating temperature range and supply voltage specifications.
