I'm trying to get this circuit using a SN74HC191 chip to work but it's producing no output to the LEDs.
My current setup so far is:
What makes this more difficult is that the datasheet for the SN74HC191 has no truth/function table so I'm not sure which switches needs to be high/low. Please could anyone provide some help?
Edit: This is the datasheet.
I have now actually found another datasheet with a truth table. However, even with the same H/L settings for "Count up", it still does not produce any LED output.
