Ok that's good to hear, you will have to put that inline for the pH circuit and anything else you might have plugged in. The eeprom, clock and LED channels are all on I2C so the clock is a good indicator if the I2C drops out as it goes to 2009. So yeah connect the input of buffer as close as possible to SCL/SDA pins on controller and plug pH circuit into it and you should be ok.
