The DS1481 is a bridge chip that enables communication between a parallel interface and a 1-Wire® bus. It supports regular and overdrive 1-Wire communication speeds and derives 1-Wire timing from an internal timing generator. No external components are needed to support the timing generator. While the device is often used in conjunction with a personal computer parallel port controller, it can also be configured to operate with the parallel interface of a microcontroller. DS1481 devices can also be cascaded to support multi-master configurations.
