DS2482S-800+

DS2482S-800+ is an 8-channel 1-wire host. It is an I²C-to-1-Wire® bridge device that interfaces directly to standard (100KHz, max) or fast (400KHz, max) I²C hosts to perform bidirectional protocol conversion between the I²C host and any downstream 1-wire server devices. Relative to any attached 1-wire server device, the DS2482-800 is a 1-wire host. Internal factory-trimmed timers relieve the system host processor from generating time-critical 1-wire waveforms, supporting both standard and overdrive 1-wire communication speeds. To optimize 1-wire waveform generation, the DS2482-800 performs slew-rate control on rising and falling 1-wire edges and has a programmable feature to mask the fast presence pulse edge that some 1-wire server devices can generate. Typical applications include wireless base stations, central office switches, PBXs, rack-based servers, and medical clinical diagnostic equipment.
