Overview

The ISO7760DWR is a high-performance, six-channel digital isolator providing 5000Vrms isolation in a 16-SOIC package. It utilizes Texas Instruments capacitive coupling technology to enable 100Mbps data rates with high electromagnetic immunity and low power consumption of 1.4mA per channel. This device is designed to protect sensitive circuitry from high-voltage transients while maintaining signal integrity across a wide 2.25V to 5.5V supply range.

Why Choose This Part

It offers industry-leading common mode transient immunity (CMTI) of 85kV/us minimum, ensuring reliable data transmission in noisy environments. The device features a long projected lifetime of over 30 years and includes robust ESD protection of +/-8kV across the isolation barrier. Its low propagation delay of 16ns max makes it suitable for timing-critical high-speed digital communication.

Applications

Industrial Automation
Providing signal isolation for PLC modules and motor control logic to prevent ground loop interference.
Multi-Channel SPI Isolation
Protecting high-speed serial peripheral interfaces where multiple unidirectional data lines must cross an isolation barrier.
Solar Inverters
Isolating control signals from high-voltage DC buses in renewable energy power conversion systems.
Medical Equipment
Ensuring patient safety by providing robust 5000Vrms galvanic isolation in diagnostic or monitoring hardware.

Getting Started

To evaluate this isolator, use the ISO776x evaluation module (EVM) which allows for signal integrity testing across various supply voltages. Ensure that bypass capacitors of 0.1uF are placed as close as possible to the VCC pins on both sides of the isolation barrier to maintain stability. For PCB layout, strictly observe the creepage and clearance requirements for 5000Vrms rating by keeping the area under the IC free of copper traces.
