IL3185-3E

Digital Isolators Overview

The IL3185-3E is a galvanically isolated, differential bus transceiver designed for bidirectional data communication over balanced transmission lines. It supports RS422 and RS485 protocols with a data rate of 5 Mbps. The device operates on 3 V to 5 V power supplies and provides 2500Vrms isolation voltage. It features 15 kV/µs common mode transient immunity (CMTI) and 15 kV bus ESD protection. The component is housed in a 16-SOIC package and supports up to 32 nodes.

Digital Isolators Feature Summary

• Galvanic isolation for differential bus transceivers
• Supports RS422 and RS485 protocols
• High common mode transient immunity
• Robust bus ESD protection

Digital Isolators Applications

• Bidirectional data communication over balanced transmission lines
• Industrial control systems requiring galvanic isolation
• RS485 and RS422 network interfaces

Digital Isolators Procurement Notes

Verify the specific suffix '3E' against the manufacturer's datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the operating temperature range of -40°C to 85°C aligns with your environmental conditions. Confirm RoHS3 compliance status if required by your supply chain regulations before finalizing procurement.

Digital Isolators Selection Notes

Select this component when designing systems requiring low-cost passive input RS-485 or RS422 isolation. It is suitable for applications needing high CMTI and ESD protection without active biasing. Consider the 16-SOIC package size and 5 Mbps speed limit when evaluating compatibility with existing PCB layouts and communication standards.

Digital Isolators Part Context

This part belongs to the IL3185 series of digital isolators from NVE Corporation. It is specifically engineered as a low-cost solution for isolated serial communication. The series includes variants like the IL3122, sharing similar isolation technologies but potentially differing in protocol support or node capacity.

Digital Isolators Replacement Considerations

Check for direct substitutes within the IL3185 family or other NVE isolation products. Verify that any replacement maintains the same 16-SOIC footprint, 5 Mbps speed, and 2500Vrms isolation rating to ensure functional equivalence.
