[time-nuts] Switching transistors, current sources, nonidealties and noise

Once upon a time I came across a document from National Semiconductor that talked about their transistor product line.  At the time they made less than 100 different transistor dies... but sold them under 10,000+ different part numbers.    Some were just packaging variations.   Maybe some selection tests were done to decide what part number to sell them under,  maybe they didn't.  Checking some pricing,  the same die (in the same package) could sell for pennies or big bucks.
