Hi Rick!

For prototyping you could use SMD adapters like these:

Thanks! 8575 is great too, and as a 16-bit chip preferred, even, but not available in oldfashioned DIP format, only the lowprofile miniature... There's always something :-)

And if you use other I2C controllers you can have up to 28 IOs in one chip. (push-pull possible, but interrupts on input for only a few lines) http://www.maximintegrated.com/en/products/interface/controllers-expanders/MAX7300.html

There is also a SPI version available with similar IOs

But on the negative side you are single sourced with these parts.

For standard parts there are also 16 bit version widely available: PCF8575
