The Great Search - I2C IO Expander (Since we can't get MCP230xx)

Adafruit Industries

We've really liked using the MCP23017 https://www.digikey.com/en/products/detail/microchip-technology/MCP23017T-E-ML/964183 and MCP23008 https://www.digikey.com/en/products/detail/microchip-technology/MCP23008T-E-ML/1223120 buuuuut they're totally unavailable. Let's see if we can find some other low cost (~$1) GPIO expanders which have programmable pull-up control (once of our fav things about the MCP series!), IRQ output, and 3V or 5V functionality!
