ISO7740DWR Description

Short technical summary and product information.

The ISO7740DWR from Texas Instruments is a high-speed, reinforced, 4-channel digital isolator. It provides a robust isolation barrier suitable for demanding applications, featuring a withstand isolation voltage of 5000Vrms and a surge isolation voltage of up to 12.8kVpk. The device supports a maximum data rate of 100Mbps and offers a common-mode transient immunity (CMTI) of 85kV/µs.

 

Designed for general-purpose isolation, the ISO7740DWR operates across a wide temperature range of -55°C to 125°C. It is available in a 16-SOIC package with surface mount technology. The isolator supports unidirectional data flow with 4 forward and 0 reverse channels, and features a propagation delay of 16ns typical.

 

This digital isolator is built with capacitive coupling technology, ensuring reliable performance in systems requiring high levels of electrical isolation. Its robust EMC characteristics and system-level immunity to ESD, EFT, and surge make it suitable for various industrial and automotive applications.
