As stated above already, yes ... but ... note ... that you can not then tie the address bits A0 .. A2 all to ground for additional MCP23017s - they will need different addresses to be set. That ... |

| Well, you still have the same issue of driving a chip running at 5V with a 3.3V logic signal. The 23017 doesn't resolve that any more than a nand gate does. It's great for adding more I/O's if you n ... | |
