1 1 SDA
Serial-Data Input/Output Line. Open drain. Connect SDA to a pullup resistor. High impedance
for supply voltages from 0 to 3.7V.
2 2 SCL
Serial-Data Clock Input. Open drain. Connect SCL to a pullup resistor. High impedance for
supply voltages from 0 to 3.7V.
3 3 OS Overtemperature Shutdown Output. Open drain. Connect OS to a pullup resistor.
4 4 GND Ground
5 — A2
I
2
C Slave Address Input. Connect A2 to GND or V
