7.5.1.3 Serial Bus Address

To communicate with the TMP461-SP device, the master must first address slave devices using a slave address byte. The slave address byte consists of seven address bits and a direction bit indicating the intent of executing a read or write operation. The TMP461-SP allows up to nine devices to be connected to the SMBus, depending on the A0, A1 pin connections as described in Table 4. The A0 and A1 address pins must be isolated from noisy or high-frequency signals traces in order to avoid false address settings when these pins are set to a float state.
