5 SDA
SMBus/I
2
C Serial Data Input/Output. Serial data to be loaded into the part’s registers and read from these registers
is provided on this pin. Open-drain configuration; it needs a pull-up resistor.
6 SCL
Serial Clock Input. This is the clock input for the serial port. The serial clock is used to clock data into and clock data
out from any register of the ADT7408. Open-drain configuration needs a pull-up resistor.
7 EVENT# Active Low. Open-drain event output pin. Driven low on comparator level or alert interrupt.
8 V
DD
Positive Supply Power. The supply should be decoupled to ground.
