Logic Gates with Transistors – NOT Gate, AND Gate, OR Gate
Logic gates, which are one of the basic elements of digital electronics, are produced as integrated circuits. There are at least four logic gates in a single chip. For example; There are 6 note gates inside the 7404 TTL IC. There are four OR gates inside the 7402 TTL IC. There are 4 AND gates inside the 7408 TTL IC.
In some circuits it may be necessary to use one or two gates. For this, by using transistor gates instead of these integrated circuits, less space is occupied in the circuit.
One transistor (BC547) and two resistors are sufficient for the NOT gate. For AND and OR logic gates, two transistors and two resistors are sufficient.
The experiments seen in the circuit diagrams were made and uploaded to our youtube channel, millivolt NET.
