X9C104S with esp8266

Hi,
I'm trying to connect an X9C104S with an esp8266ex but it doesn't work.
I tried the x9c library and other samples found on internet but nothing.
I tested before X9C103S with Arduino nano v3 and it works fine but now I want to use an esp8266.

Someone can help me with the correct pinout connection ?

Thanks in advance

Making the XC910x work with ESP8266 isn’t easy because it’s a 5 volt only part. You’ll need a 5 volt supply and a level translator to handle the 3.3 to 5 volt conversion. What what you trying to control? Most digital pots are limited to the supply voltage on all pins, the XC910x can handle +/-8 volts.
