IL 721VE

Overview

The IL 721VE is a high-speed dual-channel digital isolator manufactured by NVE Corp. It operates within an extended temperature range of -40°C to +125°C and utilizes a 16-SOIC surface-mount package with a width of 7.50mm. The device supports data rates up to 110Mbps, ensuring efficient signal transmission across isolation barriers. Key electrical characteristics include a maximum propagation delay of 15ns for both low-to-high and high-to-low transitions, with a maximum pulse width distortion of 3ns. These specifications make it suitable for applications requiring reliable digital communication in electrically noisy environments.

Feature Summary
