Pin Functions

PIN TYPE DESCRIPTION
NAME NO.
ADD 9 Digital Input Address select. Connect to GND, V+, SDA, or SCL.
D1+ 6 Analog input Positive connection to remote temperature sensors. A total of 4 remote channels are supported. An unused channel must be connected to D–.
D2+ 5 Analog input Positive connection to remote temperature sensors. A total of 4 remote channels are supported. An unused channel must be connected to D–.
D3+ 4 Analog input Positive connection to remote temperature sensors. A total of 4 remote channels are supported. An unused channel must be connected to D–.
D4+ 3 Analog input Positive connection to remote temperature sensors. A total of 4 remote channels are supported. An unused channel must be connected to D–.
D– 7 Analog input Negative connection to remote temperature sensors. Common for 4 remote channels.
GND 8 Ground Supply ground connection
NC 1, 2, 15, 16 — No connection, may be left floating or connected to GND or V+
SCL 13 Digital input Serial clock line for I2C or SMBus compatible two-wire interface.
Input; requires a pullup resistor to a voltage between 1.7 V and 3.6 V (not necessarily V+) if driven by an open-drain output.
SDA 12 Bidirectional digital input-output Serial data line for I2C- or SMBus compatible two-wire interface. Open-drain; requires a pullup resistor to a voltage between 1.7 V and 3.6 V, not necessarily V+.
THERM 10 Digital output Thermal shutdown or fan-control pin.
Active low; open-drain; requires a pullup resistor to a voltage between 1.7 V and 3.6 V, not necessarily V+. If this pin is not used it may be left open or grounded.
THERM2 11 Digital output Second THERM output.
Active low; open-drain; requires a pullup resistor to a voltage between 1.7 V and 3.6 V, not necessarily V+. If this pin is not used it may be left open or grounded.
V+ 14 Power supply Positive supply voltage, 1.7 V to 3.6 V; requires 0.1-µF bypass capacitor to ground.
