And non-gate chip (non-gate chip model)

74LS20 is not withNot gate?

1, LS20 is a double quad input and non gate, that is, two independent quad input and non gates: Y1= (A1B1C1D1) take non, Y2= (A2B2C2D2) take non, Y1 and Y2 logical values are independent. If the logical values of Y1 and Y2 are always opposite, the input ABCD2 can be connected in parallel to Y1.

2, ls20 is a commonly used double 4 input and non-gate integrated circuit, commonly used in a variety of digital circuits and single-chip microcomputer systems, its logic function is to complete the four input logic and non-computing functions. 74ls2The pin diagram of 0 is as follows: 74ls20 includes two 4 input and not gates, containing two sets of 4 and not gates. Among them, the first group: 5 input 6 output; Group 2:113 inputs and 8 outputs.

3, ls20 is two 4 input and not gates, including two groups of 4 and not gates the first group: 1,2,4,5 connected to the circuit input, 6 connected to the circuit output. The second group: 9,10,12,13 connected to the circuit input, 8 connected to the circuit output. Pins 3 and 11 are empty and do not connect cables.

4, LS20 and 74LS00 function: 74LS00 is a double input and non-gate,74LS20 is a four-input and not-gate, which implements the corresponding logic function. And not gate is a combination of and gate and not gate, first performing and operation, then performing non-operation. The and input requires two, and if the input is represented by 0 and 1, then the result of the and operation is the product of these two numbers.

5, LS20 is a 2-4 input and not gate, that is, there are two 4 input and not gates in a piece. 74LS30 is a single 8 input and no gate, that is, there is only one 8 input and no gate in a slice.

6, LS00 is a double input and non-gate, 74LS20 is a four input and non-gateThey implement the corresponding logical functions. A basic logic circuit in electrotechnics that is superimposed on a gate and a non-gate, having two inputs and one output. The logic gates in CMOS circuits are not gates, and gates, and not gates, or not gates, or gates, XOR gates, XOR gates, Schmidt trigger gates, buffers, drivers, etc.

00 What is the chip gate

ls00 is 4 two input and non gate its logic function is and non gate chip : 0 out of 1 and non gate coreFor ttl gate circuit and non-gate chip , pin suspension is equivalent to "1". When 1b is suspended, it is equivalent to 1b=1, and 1y=1a, how 1a changes, 1y changes accordingly.

LS00 belongs to the TTL gate series. It is an internal and non-gate chip containing four double input and non-gate chip , its 14 pins connected to 5v voltage, 7 pins. 74LS20 has two 4 input and NO gates, including two groups of 4 and no gatesWhen all inputs are low. CD4023: This chip is only suitable for CMOS interface.

Three input or non-gate chip models are as follows: SN74LS27N, 74AC4075, CD4075. SN74LS27N: This is a three-input or non-gate chip produced by TexasInstruments in a DIP-14 package with a wide operating temperature range and high performance. 74AC4075: This is a three-input or non-gate chip produced by FairchildSemiconductor, adoptedThe SOIC-14 package features low power consumption and high speed.

, 7410, and 7420. According to the inquiry of the official website of Huaqiang Electronics, the integrated chips of two-input and non-gate and three-input and non-gate are 7400, 7410 and 7420. The 7400 is a chip with four internal two-input and non-gates.

As for the three-input and non-gate circuit, you can use the 74LS10 chip to achieve. The 74LS10 is a three-input and non-gate chip, and its pin diagram and truth table can be found in the chip manual. Pin it to the input as instructed in the manualAfter the output is correctly connected, the three-input and non-gate circuit can be realized. A gate switching circuit can be implemented using Mux (multiple selector) or Demux (multiple solution selector).
