DINX4 & DOUTX4 schematic verification

By Fairlightiii in Design Concepts,
Hi. I have done a schematic using Eagle with a DINX4 and a DOUTX4 populated by 16 ledrings and 16 encoders. As it was my first shematic and before going more far, I would like to know if there is any error. Second question: What about the 100uF cap between VCC and GND near the first pinheader (J1) into the DOUT (I have seen some schematics with and others without)? Suggestions are welcome. Thank you.
