Description
SMBus/I
on this pin. Open-drain configuration; needs a pull-up resistor.
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.
Over- and Undertemperature Indicator. Default power as an OS pin. Open-drain configuration; needs a pull-
up resistor.
Analog and Digital Ground.
