I tried to make a simple NPN transistor inverter so that I can use the strobe line of the parallel port to store data in two separate flip-flop IC's. (74HC174 and 74HC574) The IC that data will be stored in is based on whether the strobe is on the falling edge or the rising edge.
I connected everything including this circuit and there is no smoke, no heat or anything. I could assume my resistor choices are terrible, but I'm not sure, especially with how many changes there are to PC port designs.
For reference, the parallel port I'm using is coming from a dell laptop and I specifically disabled ACPI.
When I tested the particular circuit shown, The voltages I get from the NPN base are 0.09 and 0.69V. However, the NPN collector voltages are acceptable (0.0 something, and 4.9 something).
What would cause the NPN base voltage to be so low in both cases and how do I fix it?
