... A shutdown command may be sent via the 2–wire bus to activate the low–power standby mode. Address selection inputs allow up to eight LM75’s to share the same 2–wire bus for multi–zone monitoring. All registers can be read by the host and the INT/CMPTR output’s polarity is user programmable ...

... A5, A4, A3) are fixed to 1001[B]. The states of A2, A1 and A0 in the serial bit stream must match the states of the A2 Recommended A1 and A0 address inputs for the LM75 to respond with an Acknowledge (indicating the LM75 is on the bus and ready to accept data). The Slave Address is represented by: LM75 Slave Address ...

... Acknowledge (ACK) Acknowledge (ACK) provides a positive handshake between the host and the LM75. The host releases SDA after transmitting eight bits then generates a ninth clock cycle to allow the LM75 to pull the SDA line LOW to acknowledge that it successfully received the previous eight bits of data or address ...
