Hi, I think I am going to need an I/O expander on my current project. I have decided upon the PCA9554, but can not find a supplier in the UK! I have look in all the usual places (I know). Does anyone in the UK use/buy this part? Can you tell me where you get it from? Or does anyone know of any good Philips distributors?
