More Info ...

What are you asking?
Are you wanting to drive a transistor from an IC output?
maybe a transistor will drive an IC input?

What is the IC :?:
What will the transistor be expected to drive (and from what signal)
It is often a great help to attach a circuit diagram (or the bit in question).
