DS28E17 - Maxim Integrated

DS28E17 1-Wire-to-I2C Master Bridge

The DS28E17 is a 1-Wire slave to I2C master bridge device that interfaces directly to I2C slaves at standard (100kHz max) or fast (400kHz max). Data transfers serially by means of the 1-Wire® protocol, which requires only a single data lead and a ground return. Every DS28E17 is guaranteed to have a unique 64-bit ROM registration number that serves as a node .
