Overview
The IL 2985E is a digital isolator manufactured by NVE Corp/Isolation Products, designed for RS422 and RS485 communication interfaces. It features three channels with a voltage isolation rating of 2500Vrms. The device supports a data rate of 4Mbps and offers a common-mode transient immunity (CMTI) of 30kV/µs. It operates within a supply voltage range of 3V to 5.5V and is housed in a 16-SOIC package. The component functions as a general-purpose digital isolator utilizing GMR technology.
Feature Summary
- Provides galvanic isolation for RS422 and RS485 serial communication lines
- Utilizes Giant Magnetoresistance (GMR) sensing technology for signal transmission
- Features high common-mode transient immunity to maintain signal integrity in noisy environments
Applications
- RS422 differential bus isolation
- RS485 multi-drop network isolation
- Industrial control system signal isolation
Procurement Notes
Verify the specific suffix and revision level against the manufacturer's current datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status as historical batches may vary. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.
Selection Notes
Select this component when isolated RS422 or RS485 connectivity is required with moderate data rates up to 4Mbps. Consider the 16-SOIC footprint for PCB layout constraints. Evaluate the 2500Vrms isolation barrier suitability for the specific application's safety standards.
Part Context
This part belongs to the IL series of digital isolators from NVE, which utilize proprietary GMR technology rather than capacitive or optical coupling. The series is designed for robust performance in industrial applications requiring reliable data transmission across isolation barriers.
Replacement Considerations
IL 614 is listed as an obsolete predecessor. Verify functional equivalence if substituting with other NVE models or competitors like Broadcom ACSL-6310-00TE, ensuring pinout and electrical specifications match.
