NPN-PNP latch

There was another moment of truth in the ballast project I described in Chapter 1, when we had ordered several new boards with its innovative 2N2222-2N2907 npn-pnp latch. But the protection latch on all these boards was not working at all. Design issue We looked hard at the transistors and thought they were OK. After a couple of days we took the transistors out, finally suspecting they were faulty (maybe inadequate hfe, etc.), and then made a discovery—we learned that so-called 2222 transistors do not even have the same pinouts Each manufacturer... [Pg.187]
