6.3.4 Serial Bus Address

To communicate with the TMP102, the controller must first address target devices via a target address byte. The target address byte consists of seven address bits, and a direction bit indicating the intent of executing a read or write operation.

The TMP102 features an address pin to allow up to four devices to be addressed on a single bus. Table 6-4 describes the pin logic levels used to properly connect up to four devices.
