I spent hours trying to figure out why an op-amp wouldn't give me the
output I was expecting. It finally clicked when I read the warning on
the data sheet that pulling an input within 0.5v of V- would cause it to
latch-up and force the output to near V+ no matter the state of the
inputs. I went through a few chips thinking they were defective.... or
that I toasted one (got V+ and V- reversed, which is apparently bad for
op-amps...)
