The slotting mechanism of gschem is useful for submodules with exactly the 
same function but different pins. This is the case for the four NAND portions 
of the component. Submoduls which differ by more than just pin numbers need a
separate symbol file. Make sure, that all of the subsymbols receive the same 
refdes number in the schematic. This is the queue for gnetlist to treat them 
as one component.

In my section of gedasymbols.org  there is a 7400 symbol that does just that:

The NANDs:

The power symbol:

Good thing about the 74-series is, one power symbol can cater to many of 
them :-)
