Here is a picture of I 2 C ‘s message frame.
The control byte consists of a 4-bit control code; for the DS, this is set as binary for read and write operations. Post as a guest Name. dss1621

These bits are in effect the 3 least significant bits of the slave address. In this communication protocol the master selects a slave by sending its address to the bus, rs1621 the specific slave identifies itself by this address.
Temperature sensor DS
Basically, if you have several DS devices, you can set the hardware address for each and exclusively read up to 8 devices.
Here’s what the data sheet says: What are the address input pins used for in ds? A little addition to Andy aka ‘s answer.

Sign up using Facebook. I just bought a ds temperature sensor and started reading its datasheet.
Null 4, 10 22 Home Questions Tags Users Unanswered. As you can see there is a Slave Address field which is 7 bit long. Can somebody explain to me further the interest of having those pins?
Using the DS1631 Temperature Sensor in DS1621 Applications
I es1621 out that it have 3 pins A0,A1,A2 which as specified in the datasheet are chip address input. The next 3 bits of the control byte are the device select bits A2, A1, A0. Upon receiving the code and appropriate device select bits, the slave device outputs an acknowledge signal on the SDA line.
Your device uses I 2 Cor often called 2-wire serial communication.
