Serial data to be loaded to the part’s control register is provided on this input. Data is clocked into the control register on the rising edge of SCLK. 3 5 V Positive Supply Voltage, 2.7 V to 5.25 V. DD 4 4 SCLK Serial Clock Input. This is the clock input for the serial port. The serial clock is used to clock data out of the ADT7301’s temperature value register and to clock data into the ADT7301’s control register. 5 3 CS Chip Select Input. Logic input. The device is selected when this input is low. The SCLK input is disabled when this pin is high. 6 2 DOUT Serial Data Output. Logic output. Data is clocked out of the temperature value register at this pin. Data is clocked out on the falling edge of SCLK. 1, 8 NC No Connect. Rev.
