VCC  
Digital I/O (Open Drain). SMBus bidirectional serial data. Requires pull-up resistor.  
Digital Input (Open Drain). SMBus serial clock input. Requires pull-up resistor.  
Ground Pin.  
Power Supply. Can be powered by 3.3 V standby, if monitoring in low power states is required. VCC is also monitored  
through this pin. The ADT7468 can also be powered from a 5 V supply. Setting Bit 7 of Configuration Register ±  
(Reg. 0x40) rescales the VCC input attenuators to correctly measure a 5 V supply.

Digital Input (Open Drain). Voltage supply readouts from CPU. This value is read into the VID register (Reg. 0x43).  
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 3. Can be reconfigured as an analog input  
(AIN3) to measure the speed of 2-wire fans.  
±0  
PWM2  
Digital Output (Open Drain). Requires ±0 kΩ typical pull-up. Pulse width modulated output to control Fan 2 speed.  
Can be configured as a high or low frequency drive.

Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 2. Can be reconfigured as an analog input  
(AIN2) to measure the speed of 2-wire fans.  
Digital I/O (Open Drain). Pulse width modulated output to control speed of Fan 3 and Fan 4. Requires ±0 kΩ typical  
pull-up. Can be configured as a high or low frequency drive.  
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 4. Can be reconfigured as an analog input  
(AIN4) to measure the speed of 2-wire fans.  
GPIO  
General Purpose Open Drain Digital I/O.  
THERM  
Alternatively, the pin can be reconfigured as a bidirectional THERM pin. Can be used to time and monitor assertions  
on the THERM input. For example, this pin can be connected to the PROCHOT output of an Intel Pentium 4 processor  
or to the output of a trip point temperature sensor. This pin can also be used as an output to signal overtemperature  
conditions.  
SMBALERT Digital Output (Open Drain). This pin can be reconfigured as an SMBALERT interrupt output to signal out-of-limit  
conditions.
