2-WIRE DIGITAL TEMPERATURE SENSOR
S-5851A Series
3. Data transmission
Data is transmitted by changing the SDA line while the SCL line is “L”.
If the SDA line changes while the SCL line is “H”, the S-5851A Series goes in the start or stop condition status.

4. Acknowledgment
Data is transmitted sequentially in 8-bit. Changing the SDA line to “L” indicates that the devices on the system bus
have received data, thus the devices send an acknowledgment signal back during the 9th clock of cycle.
