Just wondering - Was drawing up a couple of circuits and had an IC internal schematic on the desk for comparison. Many of the trannies in the IC schematic appear to have multiple emitters or collectors, others don't and are drawn conventionally. Seen them for years but never thought to ask before. Do/ can embedded trannies have multiple E/Cs ? Reasons ? -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you. See http://www.piclist.com/#topics
