Anyone have LM3909 data sheets?

 Anyone have LM3909 data sheets?
A friend of mine needs to build a mouth- operated switch for his sick wife. He is using a one-shot circuit for LM3909, one of the circuit examples included in National Semi data sheets for this chip. Unfortunately, two resistor values are unreadable on his copy.  
(apparently two R's near the edge of the diagram, which might be 4.7k or 47k, or 470k.)  
 
Does anyone have the Nat Semi data book, or data sheets for LM3909 and could take a look for me? If you have the sheets which include a one-shot suggested circuit, please email me at above address. Meanwhile, I will check exactly which R's are in doubt.  
Many thanks, Stephen Delft

Stephen,  
 
National has a PDF data sheet for the chip available for download http://www.national.com/search/search.cgi/design?keywords=lm3909" TARGET="_top">here. There is an "indicating one-shot" circuit on page 14, showing two 47 ohm resistors.
