Overtemperature and Undertemperature Indicator. Logic output. Power-up default setting is as an active low
comparator interrupt. Open-drain configuration. A pull-up resistor is required, typically 10 kΩ.
Critical Overtemperature Indicator. Logic output. Power-up default polarity is active low. Open-drain configuration.
A pull-up resistor is required, typically 10 kΩ.
Analog and Digital Ground.
Positive Supply Voltage (2.7 V to 5.5 V). The supply should be decoupled with a 0.1 µF ceramic capacitor to ground.

C Serial Clock Input. The serial clock is used to clock in and clock out data to and from any register of the ADT7420.
C Serial Data Input/Output. Serial data to and from the part is provided on this pin. Open-drain configuration. A
C Serial Bus Address Selection Pin. Logic input. Connect to GND or V
C Serial Bus Address Selection Pin. Logic input. Connect to GND or V
NOTES
1. NC = NO CONNECT.
2. THE EXPOSED PAD IS CONNECTED INTERNALLY.
FOR INCREASED RELIABILITY OF THE SOLDER JOINTS
AND MAXIMUM THERMAL CAPABILITY IT IS RECOMMENDED
THAT THE PAD BE SOLDERED TO THE GROUND PLANE.
