Mar 2, 2015 at 23:26 comment added natevw Thanks for interesting the comments so far! And via that related question I came across some useful related terms "logic family" and "pin compatibility" that may be related to an eventual answer here.

Feb 28, 2015 at 0:29 comment added MarkU What you don't see in the datasheets is the actual design and manufacturing cost. A second source needs to either perform better, or have lower cost (thus potentially lower selling price, or higher profit margin) to be a viable product. Mostly these are ad hoc standards, based on the original product datasheet x second source mfgr test limits.
Feb 27, 2015 at 23:38 comment added The Photon Back in the day, the US government (military) drove a lot of the standard practice in the electronics industry. And they insisted on having multiple sources for each component. So they would demand, for example, that National would license their design to at least one other company before they'd agree to buy the part. And so National would do that.
