Texas Instruments has a nice collection of 74xx data sheets in a single 
proper PDF file at <http://focus.ti.com/lit/ug/scyd013b/scyd013b.pdf> 
("Digital Logic Pocket Data Book"), apparently covering all their 
current products (as of 2007) in the 74xx line, from single-gate 5-pin 
thingies like the 74x1G00 (single NAND gate) to 100-pin monsters like 
the 74x32543 (36-bit registered bus transceivers with 3-state outputs).
