Upon receiving the code and appropriate device select bits, the slave device outputs an acknowledge signal on the SDA line. These bits are in effect the 3 least significant bits of the slave address.

Your device uses I 2 Cor often called 2-wire serial d1s621. ChiPlusPlus 1 1 Post as a guest Name. Basically, if you have several DS devices, you can set the hardware address for each and exclusively read up to 8 devices.

What are the address input pins used for in ds?

Can somebody explain to me further the interest of having those pins? The ds162 below is set to have address This is the address you set as it is described in the datasheet and in Andy aka ‘s answer.
