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).
