ISO7761DW Digital Isolator
The ISO7761DW is a high-performance, reinforced-grade digital isolator from Texas Instruments, designed to provide robust galvanic isolation for a wide range of industrial, automotive, and personal electronics applications. This device features six independent isolation channels, offering flexible configuration options (1 forward and 5 reverse, or 5 forward and 1 reverse) to suit diverse data transmission needs across an isolation barrier. Certified to meet stringent international safety standards, it offers a high working isolation voltage of 1500 VRMS and can withstand transient isolation voltages up to 8000 VPK, ensuring reliable signal integrity and system protection in harsh electrical environments.
This digital isolator is ideally suited for isolating digital signals in industrial PLCs (Programmable Logic Controllers), solar inverters, battery management systems (BMS), and medical equipment. The primary design benefits include significant space savings, higher integration, and improved performance over legacy optocoupler-based solutions.
