Hi all,
I want to invert logic voltages using the NOT gate IC. At the 7404 output I placed a 1Kohms pot to vary the 5V output to different voltage levels. These will be used as reference set-points.
When I apply 0V to the input of the 7404, I am getting an output of 4.4 to 4.5V. Is this normal when the supply voltage applied to the IC 5V?
Also, when connecting the 1K pot to the output, the voltage the further dropping to approx. 4.3 to 4.2V. How can I prevent this from happening please?
