PCF8574AP
by HGSEMI(华冠)
When a controller needs more general-purpose I/O, the HGSEMI PCF8574AP provides an I²C-connected expansion option. This through-hole version uses a 16-pin symbol and the 16-pad DIP-16_L19.2-W6.6-P2.54-LS7.6-BL KiCad footprint. A 3D model is included with the downloadable files, allowing the placed package to appear in a board view. The symbol represents the device connections while the footprint supplies the drill and pad layout for PCB work. Its conversion has been used by 1 ProtoFlow engineer in real designs. Check the I²C and port connections in the context of the host circuit. It can be opened directly in ProtoFlow.
