ISO508P-U

Overview

The ISO508P-U is a uni-directional isolated digital coupler manufactured by Burr-Brown (TI). It provides eight channels of digital isolation within a single 24-SOIC package. The device operates with a voltage supply range of 4.5V to 5.5V and offers an isolation rating of 1500Vrms. Designed for applications requiring electrical isolation between different circuits, it features a package width of 0.295 inches (7.50mm). This component facilitates signal transmission while maintaining high-voltage separation.
