C Serial Data Input/Output. Serial data that is loaded into and read from the ADT75 registers is provided
on this pin. Open-drain configuration; needs a pull-up resistor.
2 SCL Serial Clock Input. This is the clock input for the serial port. The serial clock is used to clock in and clock out data to
and from any register of the ADT75. Open-drain configuration; needs a pull-up resistor.
3 OS/ALERT Over- and Undertemperature Indicator. Default power as an OS pin. Open-drain configuration; needs a pull-up resistor.
4 GND Analog and Digital Ground.
