- 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.
