                                                                                                    The DS2480B+T&R is a serial to 1-wire line driver in 8 pin NSOIC package. This interface chip supports standard and overdrive speeds, it connects directly to UARTs and 5V RS232 systems. Interfacing to RS232C (±12V levels) requires a passive clamping circuit and one 5V to ±12V level translator. Internal timers relieve host of burden of generating the time-critical 1-wire communication waveforms. The device can translate each character into eight 1-wire time slots thereby increasing data throughput significantly. It can be set to communicate at four different data rates, including 115.2Kbps, 57.6Kbps and 19.2Kbps with 9.6Kbps being the power-on default. This IC uses a unique protocol that merges data and control information without requiring control pins. This approach maintains compatibility to off the shelf serial to wireless converters, it allows easy realization of 1-wire media jumpers.
