Referencing datasheets in BIBTEX.

The CD4007 inverter pair is referenced as far back as papers from the early 1970's.  It's a great IC for teaching, but I really had to think of how to reference it using bibtex. I decided to go with the MISC tag.

@misc{CD4007,
    author={Texas Instruments},
    title={CD4007UB},
    url={http://www.ti.com/lit/ds/symlink/cd4007ub.pdf},
    note={original document from Harris Semiconductor},
    publisher={Texas Instruments},
    year={2012}
}

UPDATE:
Of course, once I decide on a method, I come up with a better method. Include:

\usepackage{url}

in your TEX document, and then you can have a prettier entry.
