SDA (open drain)
This is the Serial Data Input/Output pin for the 2-wire serial communication port.
SCL
This is the Serial Clock Input pin for the 2-wire serial communication port.
OS/INT (open drain)
This is the Over-Limit Signal/Interrupt Alert Output pin. It is open drain, so it needs a pull-up
resistor. In Interrupt mode, it outputs a pulse whenever the measured temperature exceeds
the programmed threshold (T
the measured temperature is above or below the threshold and hysteresis (T
GND
Ground; it is the reference for the power supply. It must be connected to system ground.
A2, A1, A0
A2, A1, and A0 are selectable address pins for the 3 LSBs of the I
