I don't, but it looks quite straightforward according to the datasheet.
Seems like a simple I2C2.writeTo(addr, my8databits) would set the outputs, I2C2.readFrom(addr,1) would read them.
EEPROM looks pretty easy as well, but the address you use has the 7th bit set, so you'd need: I2C2.writeTo(addr|64, ...) to access it.
