How can you make nand gate from and gate?
A nand gate can be made from an and gate by introducing an inverter at the output of the gate.
How NAND gate works?
A: NAND implies not and to be true both input must be hi or true <> There are two flavors of NAND gate. The positive input/negative output NAND will have a low output if and only if both inputs are high. The negative input/positive output NAND will have a high output if and only if both inputs are low.
How do you draw Nand gates to function to like an And gate?
pass the inputs through an nand gate and again pass them through inverter,which is again formed by an nand gate
What logic function is obtained by adding an inverter to the inputs of an AND gate?
NAND gate
How many minimum NOR gates is required to implement NAND gate?
A 2 input NAND gate requires 4 NOR gates.A 3 input NAND gate requires 5 NOR gates.A 4 input NAND gate requires 6 NOR gates.etc.
What is the functioning of IC CD4011?
This IC is mainly used in Inverter circuits. It's very compact and has a very high life in inverter circuits.
What are the basic building blocks of digital ICs?
Usually NAND gates or NOR gates, as these are the universal gates from which all other gates, flipflops, registers, etc. can be built. - - - - - There are four basic building blocks: gates with more than one input: AND: output high if all inputs high OR: output high if any input high gates with one input: buffers: output high if input high; these are used at the ends of long wiring runs so following gates get clear signals--IOW, they're amplifiers inverters: output low if input high A NAND gate is an AND with an inverter follower, and a NOR is an OR with an inverter follower.
Can nand be inhibitted or disabled?
I suppose so. If a three input NAND is used as a two input device, the third input can be viewed as an inhibit input. Also some NAND devices can be "3 stated" where the output goes to a high impedance.
What are the fundamental logical gates?
The inverter, which returns the reverse of the input. The AND gate which returns a high output if and only if both inputs are high. The OR gate, which returns a high output if either or both inputs are high. The NAND and NOR gates return the opposite of their counterparts. They are basically the AND and OR gates with an inverter after them. The XOR gate is the exclusive OR gate; it returns a high output it either input is high, but not both. Every binary combination of outputs can be made from these operators. In fact, you don't even need all of them. The NAND and the NOR gate can both create every other gate.
What are the two types of digital logic?
AOI logic, which uses AND, OR,and INVERTER(NOT) gates NAND/NOR Logic, this uses only NAND or NOR gates respectively.
Why XOR and XNOR gate is not known as universal gates?
All other logic gates can be made using XOR and XNOR, but to get NOT, you need to do (input) XOR 1 or (input) XNOR 0, but with NAND, you don't need 1: (input) NAND (input).
How do you make an eight input AND gate out of transistors?
One way to make an eight input AND gate out of transistors... Start with one transistor, NPN. Ground the emitter. Connect the collector to Vcc with a resistor. Connect the base to Vcc through two resistors, picked to drive the transistor into saturation. The input of that stage is the junction of the two resistors. If you ground that input, the transistor cuts off, and the collector goes high. Unground the input, and the collector goes low. OK. Now you have an inverter. Build eight of them, but only use one collector resistor, and tie all of the collectors together. If any one input is high, the output is low. If all inputs are low, the output is high. OK. Now you have an 8 input negative logic NAND gate. Follow it up with another inverter stage, reversing the output. OK. Now you still have an 8 input NAND gate, with the output high true. If you want the inputs to be high true also, connect each one to an inverter. This will use 17 transistors, and you will have an 8 input positive logic AND gate.
