See Ordering Information for details.	DS2480B DS2482-800	The DS1481 is not recommended for new designs and no drop-in replacement is available. The DS2482-800 (a non drop-in) replacement allows for design of 1-Wire network lengths greater than 3 inches.

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.
