Hi all. A rather elementary question I suppose, but I would just like to know if it is okay to connect the base of a transistor to a higher voltage than the collector.
I have a microcontroller operating off 5V but one of the inputs is coming from a 12V signal, so could I just use the transistor to ground the port pin when the 12V signal is supplied, or would there be a better way to do this? I had initially planned to use a voltage regulator but thought it would be over-kill.
Any thoughts on this? Thanks
