The ones I've made, most often 30V for a bi-directional solenoid, have a pullup resistor from the high side PNP base to 30V and an NPN pulldown transistor to ground the PNP's base. The base of the NPN can be safely driven with a PIC -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you. See http://www.piclist.com/#topics
