I haven't found a 74S14 listed in any of my catalogs.  However, I have found
a 74F14 listed in my 1988 Arrow Catalog (1-800-93-ARROW) as well as a recent
(1991 or 1992) American Design Components Catalog (1-800-776-3700).  The 74F
series is less power and usually faster than the 74S.  I hope this helps.
If you order from Arrow, try Motorola part MC74F14N (stock #1439CSL) or the
Signetic part N74F14N (stock #9778BPT).  If you order from ADC, you take what
they have stocked under part number 74F14.
