A standard NOT gate will have just one input. It will change its value to the opposite digital value for the output.
ans. 3 nand gates resoon :- OR GATE :- x+y NAND GATE :- x'+y' LOGIC :-so the logic is is we apply NAND to the inputs x' and y' instead of xand y we would get x+y DESIGN PROCEDURE 1. for inverting the input x and y can be done by NAND gates , 2. take a NAND gate and pass both x in both the inputs it means x NAND x gives you x' 3. follow similar procedure for inverting y 4. and then all the outputs of those NAND gates as the inputs of another NAND gate
An AND gate
The XOR (exclusive OR) gate detects if the inputs are different. It outputs a high signal (1) when the inputs are not the same (one input is high and the other is low) and outputs a low signal (0) when the inputs are the same. Thus, it effectively identifies the difference between the two inputs.
Its a very versatile chip. It can be used in many places where logic control is required. As there are four identical NOR gates in one package, the inputs and outputs can be configured to make up quite complicated logic gates. Being a NOR gate, the the output will be at supply level, until one or both of the inputs are taken high. At which point the output will go low. The uses are many and varied. The 4000 series of chip are CMOS, so they can work at voltages between 5 and 12volts at low current.
it's a little and basic integrated circuit that makes calculations regarding Boole's logic (true/false) they can make various operations instantly regarding as the type of logic gate based on the 2 inputs, giving the result as output. they can make the OR operand, And, Xor,Not and a combination of them (cheaper) Nor,Nand,XNor it's the base for digital computing.

Logic gates can be primarily divided into two categories: combinational logic gates and sequential logic gates. Combinational logic gates, such as AND, OR, and NOT gates, produce outputs based solely on the current inputs without memory. In contrast, sequential logic gates, like flip-flops and counters, consider both current inputs and past states, allowing for memory and timing functions in circuits. These divisions form the foundation for building complex digital systems.
An AND gate
A "Nand" gate is an "And" gate with an "Inverter" added to its output. To get a logic 1 output from a "Nand" gate, you need a logic 0 on both of its inputs. If I understand your question correctly, you have three "Nand" gates. Presumably the outputs of two of them are connected to the inputs of the third. Logic 1 at both inputs of the first two "Nand" gates will produce a logic 0 output from both of them. The two logic 0's are fed to the inputs of the third "Nand" gate producing a logic 0 output from the third "Nand" gate.
AND gate is A.B If two not gates are added at both inputs of and gate then output becomes A'.B' which is equal to (A+B)' by DeMorgan's law. hence the nor gate is formed Update: Put more simply, invert A and B by attaching A to both inputs of one NOR and attaching B to both inputs of another NOR, then NOR the results of the previous two NOR gates. Total of three NOR gates in a two-level implementation. NAND can obviously be created by inverting the result.
By using 5 NOR gates, we can implements half-subtractor. The inputs for 1st NOR gate are A and B, for 2nd NOR gate inputs are the output of 1st NOR gate and A input, for 3rd NOR gate inputs are the output of 1st NOR gate and B input, for 4th NOR gate the inputs are gates 2 and 3, and for last gate input is the output of the 4th gate.
The XOR (exclusive OR) gate detects if the inputs are different. It outputs a high signal (1) when the inputs are not the same (one input is high and the other is low) and outputs a low signal (0) when the inputs are the same. Thus, it effectively identifies the difference between the two inputs.
It means that C is the inverse of A. Implementing the equation C = !A in basic logic gates requires the use of an inverter. An inverter can be made from a dedicated inverter gate, if available, or from a NAND gate with n inputs, where all n inputs are connected to A.
To produce a 3-input OR gate when only 2-input OR gates are available: Use 3 OR gates Inputs to Gate A are input 1 and input 2 Input to Gate B is input 3 (if 2 inputs are necessary, include input...
TTL (Transistor-Transistor Logic) inputs typically refer to the number of inputs that a TTL device, such as a logic gate or flip-flop, can handle. Common TTL logic gates often have 2 to 4 inputs, while more complex devices like multiplexers or encoders can have larger numbers of inputs, ranging from 4 to 16 or more. The specific number of TTL inputs depends on the type and design of the device in question.
That package contains four 2-input NAND gates with Schmitt-trigger inputs.
