I/O expanders, instead of having only 8 outputs, are there any of them which have more than 8 outputs?

Instead of buying multiple 74HC165 chips and connecting a huge tangling mess to the brains and wasting huge amounts I/O pins which I should be using to do something else, I'll need I/O expanders which have more arms than legs, (More Output pins than input pins)

because my project is too awesome to deal with meer mortals, I need giants.

Suggestions only. I'm the one doing the research, if you know tell me, don't go wasting your own time scanning the entire internet because I'm the one doing that.

so a port on your mcu essentially gets double the ports, except theyre all identical

or did i miss your point?

If an expander has fewer outputs than inputs, then it's not really an expander is it? If you really can't afford to use many control pins, check out the I2C protocol.
Okey, got the names wrong. I meant output pins as in using output devices.
