Serial Data Input/Output. SDA is the input/output pin for the I 2 C serial interface. The SDA pin is an
open-drain output and requires an external pullup resistor.
Serial Clock Input. SCL is used to synchronize data movement on the I 2 C serial interface.
Supply Voltage. Power-supply input.
Do Not Connect
Ground
Sleep Input (Active Low). When taken low, the DS2741 is placed in a low-power sleep state where
all internal circuitry including the I 2 C bus is disabled. Toggling the SLP pin low and then back high
resets the device and the I 2 C bus logic.
