    SMSC SCH5555-NS Datasheet

    Looking for SMSC SCH5555-NS datasheet or pinout data. It's the SIO chip from a Dell Optiplex 7020 motherboard with a no power condition. Anyone has?
    I am struggling to repair it because I don't know which pin is doing what.
    Any help would be greatly appreciated
