How to design XOR circuit with AND gate, OR gate and NOT gate?

1. If it is NOT-gate, just combine the two inputs into one, that is, two inputs input signals at the same time, and the output will get NOT-gate signal.

2. Each input terminal is connected to the gates of an N-channel AND a P-channel MOS transistor (this is Nand gate), and the output terminal is connected to a NOT gate (inverter mentioned above) (adding a NOT gate turns NAND into AND), or the OR gate is two N-channel enhanced MOS transistors connected in parallel and two P-channel enhanced MOS transistors connected in series.

3, this is a problem of calculating electricity! The logical relationship of XOR is: when the two input signals are the same, the output is 0; When the two input signals are different, it is enough to use three AND gates and two NOT gates for the output.

4. Draw an XOR gate and an XOR gate with the simplest circuit. The simplest method is to form an XOR gate with a 2-input NAND gate 74LS00, as shown in the circuit below. A, B are two input variables, and Y is the output. The XOR gate can also be composed of a 2-input NAND gate. The circuit is as follows, using two NOT gates 74LS04.

LS00 is a NAND gate, and the exclusiveOR gate is a simplified NAND gate: exclusive OR in English, or xor for short. Xor is a mathematical operator. It is suitable for logical operation. The mathematical symbol of XOR is "_" and the computer symbol is "XOR".

Experiment 4 Trigger and Counter Experiment 5 The logic function and test of pulse generation and shaping circuit experiment 1 logic gate 1. Experimental purpose 1. Master the shape and logic functions of TTL series and CMOS series. 2. Be familiar with the test methods of various gate parameters.

LS00 is four 2-input NAND gate integrated chips. If an AND gate is formed, the result will be negated once, that is, the output will pass through the NAND gate once. If it is not a gate, the two inputs are combined into one and used for one purpose, that is, the input signal is input from both input terminals at the same time, and the output terminal gets a non-gate signal.

I'm sorry to tell you that only one 74XX00 can't do XOR.

Digital circuit knelt down and asked how to connect this picture in the test box and what chip to connect.

Digital circuit knelt down and asked how to connect this picture in the test box and what chip to connect.

1. First, connect the non-gate power supply pin to the positive power supply of the experimental box and connect the ground pin to the negative power supply. Secondly, the input pin is connected to the output pin of the digital switch on the experimental box. Finally, connect the output pin of NOT-gate to the input pin of LED lamp or digital switch on the experimental box.

2. The turn-on sequence of power supply is: first turn on the AC switch (boat switch in the experimental box), then turn on the DC switch, and finally turn on the control switches of each module. The order of power failure is just the opposite. Never electrify the wires in the experiment. The correct way is to connect the wires after the power failure and carry out the experiment.

3. Connect the VCC pin of the non-gate power supply to the positive power supply of the experimental box, and connect the GND pin of the ground to the negative power supply. Connect the input pin of the NOT gate to the output pin of the digital switch on the experimental box.

4. Select the chip 74LS74, and the pin diagram is as follows. Description: 74LS74 is a double D flip-flop triggered by rising edge. The characteristic equation of D flip-flop is a design scheme: a counter consists of flip-flops. Flip-flops have two states: 0 and 1, so a single flip-flop can represent a binary number.

5. Ground the two chip selection inputs (GG2) to select the chip. Connect the input signals (A, B, C, D) to the input terminal of the chip.

1. When you input a voltage of +5V at any pin of AB, the TTL circuit input pin is suspended at a high level regardless of whether the other pin is grounded or not.

2. XOR gate is mainly used for the control of digital circuits! XOR operation and XOR gate can realize XOR logic operation through logical NOT, logical AND and logical OR, that is. Where ""is the symbol of XOR logic operation, which is read as "XOR".

3. XOR gate can add modulo 2, so XOR gate can add binary in computer. A half adder consists of an XOR gate and an AND gate.

4. If the levels of the two inputs are different, the output is high level1; If the levels of the two inputs are the same, the output is low level 0. That is, if the two inputs are different, the XOR gate outputs a high level of 1. Application of XOR gate: XOR gate is widely used in the calculation circuit and error correction circuit of digital signal transmission.

5. Specifically, the port 14 is connected to high level, 7 is connected to ground, 13 is connected to A, 12 is connected to B,1connected to1; 10 to A, 9 to B, 8 to 2; In this way, port 3 is the output Y, that is, the function of XOR gate is realized. I hope it's not too tortuous, and it's mainly about transformation. It is good to understand the change.
