#85421 - Push-pull needed? Responding to: ???'s previous message |
Rob said:
I am trying to convert a 0 to 5volt 40khz output signal from the microcontroller up to 0 to 12 volts. Hmm, maybe the use of this single transistor inverter is not apporpriate for your application? Maybe a push-pull stage is needed, providing low source impedance not only if the output goes low, but also if the output goes high? Tell us, what you want to do with the 12V signal. Kai |
