Product Overviews

ADUM1253ASA is Ultra-Low-Power Two Channel, Bidirectional I2C Digital Isolator. It offers two open-drain channels, one unidirectional and one bidirectional for applications, such as I2C, that require data to be transmitted in both directions on the same line but have a unidirectional clock. The ADuM1253 features independent 1.71V to 5.5V supplies on both side 1 and side 2 of the isolator. The device operates up to 2MHz.
