IL 514E

Overview

The IL 514E is a general-purpose digital isolator manufactured by NVE Corp/Isolation Products. It utilizes Giant Magnetoresistance (GMR) technology to provide electrical isolation between circuits. The device features three independent channels with unidirectional signal transmission. It supports a data rate of 2Mbps and offers a basic isolation voltage of 2500Vrms. The component exhibits a common-mode transient immunity of 30kV/µs. It operates within a supply voltage range of 3V to 5.5V and is housed in a 16-SOIC package.

Feature Summary

• Utilizes GMR technology for reliable signal transmission
• Provides high common-mode transient immunity
• Features three unidirectional channels

Applications

• General purpose digital isolation
• Signal transmission in isolated circuits

Procurement Notes

Verify the specific suffix and package variant when ordering, as availability may vary. Confirm RoHS compliance status for the specific revision being procured. Check for obsolescence notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component for applications requiring moderate speed isolation with high noise immunity. Ensure the system voltage requirements align with the 3V to 5.5V operating range. Consider the 16-SOIC footprint during PCB layout design to ensure proper clearance and creepage distances are maintained.
