There are many discussion about initialization sequence, application note, command, application, bus, conversion, wire bus system, ds18b20, and idle state are explained in the datasheet. The datasheet tells us explanation around parasite power mode, temperature conversions, temperature sensor, pulse, power mode, external power supply, alarm, and temperature.
Inside the datasheet the reader can get description around temperature conversion, maxim, time slot, power supply, read time, system, temperature register, conversion time, and device. Here are chosen from this datasheet:
DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile user programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor.
Furthermore, this datasheet presents info things like power, register, transaction sequence, data, configuration, alarm condition, the bus master, and resolution.
