IL 511-1ETR7

Digital Isolators Overview

The IL511-1ETR7 is a dual-channel digital isolator from the NVE IL series, housed in an 8-TSSOP or 8-MSOP package. It supports a data rate of 2 Mbps and provides 2500 Vrms isolation voltage with a common-mode transient immunity (CMTI) of 30 kV/µs. The device operates within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Utilizes magnetic coupling technology for signal transmission across the isolation barrier
• Features a ceramic/polymer composite barrier designed for high reliability and long life
• Provides bidirectional channel capability for flexible system integration

Digital Isolators Applications

• General-purpose digital isolation in industrial control systems
• Isolation for microcontroller unit (MCU) interfaces
• Human-machine interface (HMI) peripheral connections

Digital Isolators Procurement Notes

Verify the specific suffix 'ETR7' to confirm the tape-and-reel packaging format and TSSOP/MSOP footprint. Ensure compatibility with existing board layouts requiring this specific surface-mount package style. Confirm that the 2 Mbps data rate meets the application's timing requirements before procurement.

Digital Isolators Selection Notes

Select this component when a compact surface-mount solution is required for low-speed digital isolation. The 2 Mbps rate suits applications where power consumption is critical but high bandwidth is unnecessary. Compare against the obsolete IL511-1E to ensure supply continuity and verify that the 30 kV/µs CMTI is sufficient for the noise environment.

Digital Isolators Part Context

This part belongs to the NVE IL family of digital isolators, which utilize proprietary magnetic sensor technology. The IL511 variant specifically offers two independent channels in a small outline package, distinguishing it from single-channel or higher-pin-count variants within the same product line.

Digital Isolators Replacement Considerations

The IL511-1E is listed as obsolete. The IL511-1ETR7 serves as the active replacement. Verify pinout and electrical specifications match exactly before substituting.
