Overview

The ISO7761FDW is a high-performance, six-channel digital isolator providing 5000Vrms isolation in a wide-body SOIC package. It supports data rates up to 100Mbps with low power consumption and robust electromagnetic compatibility, featuring a default output state of low (logic F).

Why Choose This Part

This device offers a high Common Mode Transient Immunity (CMTI) of 85kV/us and low propagation delay of 11ns, ensuring reliable communication in noisy environments. The 5:1 channel configuration simplifies board layout for applications requiring multiple forward and one reverse data path.

Applications

Industrial Automation
Provides high-speed signal isolation between PLCs, motor drives, and industrial sensor networks to prevent ground loop interference.
Isolated SPI/UART Communication
Enables multi-channel level translation and isolation for high-speed serial interfaces operating between 2.25V and 5.5V.
Solar Inverters
Protects control circuitry from high-voltage transients in power conversion systems while maintaining high-speed signal integrity.
