Search the Adom Wiki for the library component "PCF8574" (slug: pcf8574) at https://wiki-ufypy5dpx93o.adom.cloud/wiki/libraries/pcf8574. Pull down the KiCad symbol, footprint, and 3D model files from the wiki page's assets. Install them into my current KiCad project and register in sym-lib-table and fp-lib-table. If the page has a datasheet URL, save that too.
The PCF8574 is a remote 8-bit I/O expander with I2C interface from NXP. Provides 8 quasi-bidirectional I/O pins. Commonly used for LCD character display backpack boards and button expansion.
