I ones worked with those chips, I only had it working without the 33 pF capacitor. The MCP23017 seems a better choice, it does not need an external capacitor.

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

Yeah I prefered the 17's but i could not grab that chip at my local store so gone for the 16. I will try without the cap. Thanks for that tip
I'm now managing to do it with the philips component, but it has only 8, so i will have to make 2 other SDA, SCL lines.
