### Is oit possible to use three input in ic 7486?

If you look at the 7486 IC datasheet you can see, it have 4 independence XOR gates with 2 inputs. So you can only use 2 inputs if you see it like that. But if you understand the truth table of XOR gate you can have 3 input application using 7486 IC. Here I will show you how. 1.Get the first 2 input into the first XOR gate. 2.Then get the 3rd input together with…

### How using two-input logic gates of your choice design a circuit to determine if two 3-bit numbers are the same or different?

Three 2-input XOR gates and one 3-input NOR gate will do the work. Connect each output of each XOR gate to one input of the 3-input NOR gate and apply the two 3-bit words to the inputs of the XOR gates. If X (X2X1X0) and Y(Y2Y1Y0) are two 3-bit words, X2 and Y2 will connect to one XOR gate, X1 and Y1 to the next XOR gate and X0 and Y0 to the last XOR…

### What is the difference between XOR and XNOR Gates?

XOR 1.The output of xor gate is high only when the input are different 2.The output is low when the input are same 3.If A and B are two input the outputs expressively X NOR 1.The x nor operation is the complement of xor gate 2.The output of x nor is high only when both the input are same 3.The output of x nor is low only when both the are different

### How could you produce 3 input XOR gate if you have only 2 input XOR gate available?

you can take 2 input or gate first 2inputs and output of that gate should be given as the input for next OR gate with 3rd input Above solution will not work if all 3 inputs are True. I believe the question requires a configuration of XOR gates that will produce a True result if EXACTLY one out of three inputs is True. Specifically, if Inputs A and B are both True, the first XOR…

### Truth table for 3 input xor gate?

Exclusive Or means "one and only one of many", so the truth table of a 3 input XOR gate would be 000 0 001 1 010 1 011 0 100 1 101 0 110 0 111 0 ... or 111 1 ... see note Many references say that 3 input XOR gate's output should be 1 when the no of 1s in inputs is Odd, and 0 otherwise. So in the given truth table, when…

### How could you produce 3 input OR gate if you have only 2 input OR gate available?

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 3 and FALSE) Inputs to Gate C are outputs from Gate 1 and Gate 2 === If input 1 OR 2 is TRUE, output of Gate A will be TRUE. If input 3 is…

### How can you make a three input AND gate with a two input AND gate?

you will need 2 two input AND gates to do this. connect the output of the first to one input of the second. you now have a three input AND gate. just remember when calculating timing that 2 inputs of the 3 have twice the gate delay of the remaining input, thus the output will have skew and possibly glitches. if timing is critical or glitching can't be tolerated it may be best to use…

### Half-Subtractor circuit using NOR gates?

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.

### Description of ic 7432?

The 7432 is a TTL (transistor-transistor logic) digital silicon integrated circuit with four 2-Input OR gates usually in a 14 pin DIP (dual inline package). It operates on a single 5VDC supply. A low input (false) must be an active pulldown below 0.8V, a high input (true) must be above 2.0V while the inputs naturally float above this voltage if not driven unused inputs should be passively pulled up with resistors to reduce noise pickup…

### Design a Combinational circuit that has three input and one output the output is 1 when the binary value of the input is less than three the output is logic 0 otherwise?

If you are talking combinations, without binary number representations, then you are talking about a circuit that has a 1 output when any input is a 0. That is a 3 input NAND gate. If you are talking binary number representation, then you are talking about a circuit that has a 1 output when the inputs are 010, 001, or 000. Use a 3 to 8 decoder, with an OR gate on the low three…

### How do you convert gray code to binary code?

To convert from Gray code to binary code, proceed as follows: Step 1: Fix the most-significant bit (always the same for both). Step 2: XOR the most recent binary bit with the next bit in the Gray. Fix the result as the next binary bit. Step 3. Repeat step 2 until all digits are fixed. Examples (bold indicates a fixed binary bit): Gray: 0111 = 0 XOR 1 = 1 XOR 1 = 0 XOR…

### How do you convert bcd into Gray code?

Binary coded decimal (BCD) requires a minimum of 4 bits to represent all possible digits from 0 to 9. There are ten possible configurations for a BCD with the following corresponding Gray codes, which also require a minimum of 4 bits: Digit : BCD : Gray 0 : 0000 : 0000 1 : 0001 : 0001 2 : 0010 : 0011 3 : 0011 : 0010 4 : 0100 : 0110 5 : 0101…

### Can you write a CPP program to displaying XOR truth table using logical AND OR and NOT?

I do not believe this is possible. The only solution I could come up with does not involve either OR or NOT, but it does use the plus and minus operators combined with the logical AND operator (more formally termed addition modulo 2, or addition without carry). The following C++ program demonstrates that the function, XOR(), correctly emulates the logical XOR operator (^). #include <iostream> int XOR( int x, int y ) { return(( x…
