ADI ADUM1250ARZ

磁耦合22500Vrms

Overview

The ADUM1250ARZ are hot swappable digital isolators with nonlatching, bidirectional communication channels that are compatible with I2C interfaces. This eliminates the need for splitting I2C signals into separate transmit and receive signals for use with standalone optocouplers. The ADUM1250ARZ provides two bidirectional channels, supporting a complete isolated I2C interface.
