7.5.3 Device Address

To communicate with the TMP110, the controller must first address target devices through an address byte. The address byte has seven address bits and a read-write (R/W) bit that indicates the intent of executing a read or write operation. The TMP110D features an address pin to allow up to four devices to be addressed on a single bus. Table 7-8 describes the pin logic levels used to properly connect up to eight devices on the same I2C bus. This table also describes four different address options available when ALERT pin is used.
