TTL Voltage Levels for “High” / “Low”. Logic Circuits, 5/101

If you connect your voltmeter to an inverter package - or any other TTL circuit actually - you may expect the display to show you some clear value.
For instance if the expected logic state is “0”, you may expect to see 0.0V on the DMM display.
If the expected logic state is “1” or High, you are looking for 5.0V on the DMM display.
In reality, as the power supply voltage for TTL circuits is +5V, the meter can show you any possible value you may imagine between 0.0V to 5.0V, like 0.73 or 1.64 or 2.98 and so on.
How do you put order then in the readings?
This is exactly the purpose of the video, to make the readings understandable.
As a reference, look in the folder “Binary and Logic Circuits” on google drive: drive.google.c...
For the rough understanding of the TTL Voltage Levels, we should be good enough for now.
More details will emerge of course as we advance with the gates.
Thanks for watching and CU next Tuesday!
