This is a prelab i am working on: we have a 74HC04 inverter, whose pin 1 is connected to the DIP switch (switch connected to 5V source and ground), pin 2 is connected to 1) a load (R + LED) that connects back to the source 2) a load (R + LED) that is properly connected to the ground pin 7 is connected to the ground. And the LEDs light up as the prelab describes, so i assume i built the circuit correctly. So, it asks to measure Voh, Vol... but i don't know where the output is! I drew the circuit. If pin 7 is output, my multimeter does not detect a thing! what is the output in this case and how do i measure it? So, generally if you deal with LCs, are pin1 and 2 usually considered inputs or is there no convention? Thanks sooo much again and again!
