SCLSerial Clock
SDASerial Data
A0 to A3Address
VHo/RHo to VH3/RH3, VLo/RLo to VL3/RL3Potentiometers Pins (terminal equivalent)
VWo/Rwo to Vw3/Rw3Potentiometer Pins (wiper equivalent)

 

The SCL is used to clock data into and out of the X9241ASDA is a bidirectional pin used to transfer data into and out of the deviceThe Address inputs are used to set the least significant 4-bits of the 8-bit slave addressThe RH and RL inputs are equivalent to the terminal connections on either end of a mechanical potentiometerVW/RW (wiper outputs) are equivalent to the wiper output of a mechanical potentiometer.
