IL41050TFD-1E

Overview

The IL41050TFD-1E is a digital isolator manufactured by NVE Corp/Isolation Products, belonging to the IsoLoop series. It utilizes Giant Magnetoresistive (GMR) technology to provide galvanic isolation for high-speed data transmission. The device features two independent channels with unidirectional signal flow, designed specifically for Controller Area Network (CAN) bus applications. It supports data rates up to 1 Mbps and offers a minimum common-mode transient immunity of 30 kV/µs. The unit operates within a supply voltage range of 3 V to 5.5 V on the input side and 4.75 V to 5.25 V on the output side. It is housed in a 16-SOIC package with a width of 7.50 mm and functions reliably across an extended temperature range from -55°C to 125°C.

Feature Summary

• Utilizes GMR technology for robust signal isolation without capacitive coupling limitations
• Provides dedicated isolation for CAN bus communication protocols
• Features high common-mode transient immunity for noisy environments

Applications

• Industrial automation systems requiring isolated CAN interfaces
• Automotive electronic control units (ECUs)
• Medical equipment with strict isolation requirements

Procurement Notes

Verify the specific suffix 'FD-1E' against the manufacturer's official documentation to confirm tape-and-reel packaging and any distinct marking variations. Ensure compatibility with standard 16-SOIC footprint designs during procurement planning.

Selection Notes

Select this component when designing circuits that require reliable isolation for CAN networks in harsh electromagnetic environments. Consider the 16-SOIC package constraints and verify that the operating voltage ranges align with the system's power supply architecture.
