1

SDA

SMBus/I2C Serial Data Input/Output. Serial data that is loaded into and read from the ADT75 registers is provided

on this pin. Open-drain configuration; needs a pull-up resistor.

2

SCL

Serial Clock Input. This is the clock input for the serial port. The serial clock is used to clock in and clock out data to

and from any register of the ADT75. Open-drain configuration; needs a pull-up resistor.

3

OS/ALERT Over- and Undertemperature Indicator. Default power as an OS pin. Open-drain configuration; needs a pull-

up resistor.

4

GND

Analog and Digital Ground.

A0

SMBus/I2C Serial Bus Address Selection Pin. Logic input. Can be set to GND or VDD.

SMBus/I2C Serial Bus Address Selection Pin. Logic input. Can be set to GND or VDD.

SMBus/I2C Serial Bus Address Selection Pin. Logic input. Can be set to GND or VDD.

8

VDD

Positive Supply Voltage, 3 V to 5.5 V. The supply should be decoupled to ground.
