This is a digital temperature sensor, that is already calibrated. The measurement is done where the sensor is, no need for long insulated wire or complicated ADC design.
This sensor is therefore also perfect for use with a Raspberry Pi, as it is not analogic, all the data is transmitted in digital One Wire protocol.
The very popular 595 shift register chip of the 74 series is used a lot by hobbyis because of its wide availability, good speed and simplicity. Just plug it on an arduino like shown in the tutorials and youi have 8 more outputs, put two and you have 16 more outputs ! (up to a lot of them actually, with only three pins !)
