This chip allows to have up to 8 digital inputs/outputs connected through I2C bus. Thanks to three address lines (which can be set to 0 or 1), a single I2C bus can handle up to 4 such chips. This means you are able to extend the number of Arduino I/O ports by 64 or 128 in case of using PCF8574A expanders (not sold by Nettigo).
The Arduino library for PCF8574P is in Files section.
Check out the examples of using this chip on our blog Starter Kit (not translated yet).
