Logic Gates (AND, OR, NOT Gates) Part 1/2

In this video, I will explain the working principle of logic gates that form the basis of all electronic devices we use, which we can encounter in many areas in daily life. When we say digital electronics, the first thing that comes to our mind is logic gates. When numerical expressions are mentioned, level 1, level 0, logic circuits or in other words logic gates come to mind. This type of integrated circuit consists of circuits made with basic electronic elements such as transistors, resistors and diodes.
Logic gates form the basis of digital systems. Input information is transferred to the output by performing Boolean mathematics operations. Operations are performed on the logical expressions Logic-1 and Logic-0. The reciprocal of 1 logic expression is defined as 5V, and the reciprocal of 0 logic expression is defined as 0V.
Now let's look at how to number the pins of the logic gates. When we hold it to read the text on the IC, there is a notch on the left side. The pins are numbered starting from this notch. Logic gate ICs are generally 14 pins.
For example, when we look at the internal structure of the 7408 IC, we see that it consists of four AND gates. This logic gate has two inputs and one output. When we go into a little more detail and look inside an AND gate, we see that there is a circuit consisting of two BJT transistors and resistors.
There are 7 types of basic logic gate circuits: They are the AND gate, OR gate, NOT gate, NAND gate, NOR gate, XOR gate, and finally the XNOR gate. These circuits, also known as logic gates, produce appropriate logical results with 1 and 0 data received from the input, namely 5V and 0V, within a certain Boolean Algebra framework. That is why we can say that they are indispensable elements of digital electronic systems. Now, let's examine the symbols, mathematical expressions and truth tables of these logic gates one by one. In order for the video not to be too long and boring, I will explain the AND, OR and NOT gates in this video. In the next video, I will explain other logic gates.

Thank you for breaking logic gates into bits...I understand perfectly...🙏

[@eeapplications]

Aaa super. Glad if it was useful 😊

[@juanmamani2110]

Absolutely useful! first time a I found a video of this quality content! thanks for sharing.

[@ntsikakortjan7676]

Just what I needed, clear and well presented. Thanks mate 🙇🏾‍♂️

[@kabandajamir9844]

The world's best teacher thanks

[@danieladams4289]

Very enlightening. Thank you for the eloquently easy explanations. I'm on the edge of my seat for video 2 .. meanwhile I want to start experimenting. 🤙

[@eeapplications]

Thank you very much. The other video will be live in a week as always 😊

[@shuaibification1]

Excellent explanation.

[@ruben.g.m.moreno]

Thank you very much, your class is wonderful. However, I would like to know what this site is for integrated circuits for Proteus. Thanks again!

[@hectormata449]

Excellent and complete explanation of the function of these logic gates.

[@eeapplications]

Thank you so much ☺️🙏

[@georgembowa8919]

Simple, concise yet useful information

[@eeapplications]

Thank you so much ☺️

[@antonworm]

Thanks, very clear.

[@eeapplications]

Thank you so much ☺️

[@leploeo7145]

Thanks

[@leploeo7145]

👍👍

[@vijitkothari6502]

This is exactly what I doubt will happen. We teach if button is off it means that input is 0. But in some videos i have seen teachers inputting a GND signal where it should be 0.

[@Vpg001]

In the not gate example, how is pin 2 positively charged?

[@Extasio_123]

What program are you using for this tutorial

logic 1 = 5V, in this chip, but not in all situations, 3.3V or lower can be used ...
