Digital Input (Open Drain). SMBus serial clock input. Requires SMBus pull-up.  
Ground Pin for the ADT7467.  
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 ADT7467 can also be powered from a 5 V supply. Setting Bit 7 of Configuration Register ±  
(0x40) rescales the VCC input attenuators to correctly measure a 5 V supply.

TACH3  
PWM2  
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 (low frequency mode only).  
Digital Output (Open Drain). Requires ±0 kΩ typical pull-up. Pulse width modulated output to control the speed of  
Fan 2. Can be configured as a high or low frequency drive.  
Digital Output (Open Drain). This pin can be reconfigured as an
