Hi,
Bellow shown the PNP driver circuit.
Please anyone can tell me why the input=LOW then the Emitter=UN-know logic? The design is it correct? The 7405 output is open-collector, If the 7405 input is un-know logic so what is the actual 7405 output?
How to design the Non-Inverting Driver using PNP transistor?
Thank You
