I had a couple of things I wanted to figure out about the SG3525 and
got to looking at the schematics for the oscillator and the error
amplifier at the bottom of page 6 of the datasheet. (I wanted to
figure out how to use the sync pin, since the datasheet doesn't
explain it. And how low the common mode of the error amplifier goes,
since the datasheet only states that it includes Vref, or 5 volts.)

What does the symbol that looks like a transistor with two collectors
represent and if you can, help me figure out the answers to my two
questions.
