We're in shortage of PCA9535HFHP for a production planning. Need your help to advise if we can use PCA9555AHF,128 as alternative. Looks like these two parts are pin-to-pin compatible and no change on software control, am I right? It's used for I2C-to-GPIO expanding and we don't care much upon power consumption, I/O toggling speed, etc. There're external pull-up resistors on our board for all the expanded I/Os.
