Need my output to drive two transistors, turning one on while turning the other off. How do I configure this? Thanks!!

Try this design, when Q1 is on, Q2 is off, and viceversa..

 

You can do this with an NPN and PNP transistor. Could you provide more details?

1. What is the voltage and current (max) provided by this output?
2. What are the transistors driving (volts and amps)?
3. Do you have some specific transistors in mind or on hand you are trying to use?
