hi,
Assume for instance, that you connect the basis of a transistor directly to pin, ...
Reading this example in manuals, I always ask myself: which stupid man does it? In the same manual they explain about how the pFETs work and it says that while "loop-back feature" cannot recognize logical One then strong pFET3 will not be opened! And so the question: what is the reason to "connect the basis of a transistor directly to pin" if such schematic never opens that transistor??? What do I miss?

Thanks,
