Overview

The ISO7761DBQR is a high-performance, six-channel digital isolator providing reinforced isolation up to 5000 Vrms. It features a 5 forward and 1 reverse channel configuration, designed to protect low-voltage CMOS or LVCMOS circuitry from high-voltage transients while maintaining high electromagnetic immunity.

Why Choose This Part

This device offers high CMTI of 100 kV/microsecond and a long lifetime of over 40 years at high working voltages. Its low power consumption and low propagation delay make it ideal for high-speed digital communication across an isolation barrier.

Applications

Industrial Automation
Used in PLC and DCS systems to isolate field-side sensors and actuators from the sensitive control logic.
Motor Control
Provides signal isolation between high-power inverter stages and the low-voltage motor controller.
Solar Inverters
Protects communication interfaces and control circuits from high-voltage DC buses in photovoltaic systems.

Getting Started

Place the IC across a minimum 8mm creepage gap on the PCB to maintain reinforced isolation ratings. Ensure local decoupling capacitors of 0.1 microfarads are placed as close to the VCC1 and VCC2 pins as possible to maintain signal integrity during high-speed switching.
