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 address in the 1-Wire network. Multiple DS28E17 devices can coexist with other devices in the 1-Wire network and be accessed individually without affecting other devices. The DS28E17 allows using complex I2C devices such as display controllers, ADCs, DACs, I2C sensors, etc. in a 1-Wire environment. Each self-timed DS28E17 provides 1-Wire access for a single I2C interface.
