Another type of Demultiplexer is the 24-pin, 74LS154 which is a 4-bit to 16-line Demultiplexer/decoder. Here the individual output positions are selected using a 4-bit binary coded input. Like multiplexers, Demultiplexers can also be cascaded together to form higher order Demultiplexers Step 2. Now, it turns to construct the truth table for 2 to 4 decoder. E input can be considered as the control input. Mean to say, If E equals to 0 then the decoder would be considered as disabled regardless of what inputs are, If E equals to 1 then the decoder would work as per inputs 4 to 16 line Decoder. In the 4 to 16 line decoder, there is a total of 16 outputs, i.e., Y 0, Y 1, Y 2 Y 16 and four inputs, i.e., A 0, A1, A 2, and A 3.

How to build a 4x16 decoder using ONLY two 2x4 decoders? Following the steps we took in the lecture, we are supposed to build a 4x16 decoder. So here taking k to be 4, k is even, so we will have \\$2^k\\$ so \\$2^4 = 16\\$ AND gates & 2 decoders each of size \\$2^{k/2}\\$ so \\$2^2 = 4\\$. So we have 16 AND gates & two 2x4 decoders It is called a decoder because it does the reverse of encoding, but we will begin our study of encoders and decoders with decoders because they are simpler to design. One of the most frequently asked questions, what is the main difference between demultiplexer and decoder is that a demultiplexer is a combinational circuit that accepts only one input and directs it into one of the several outputs

In some kinds of decoders, they have below 2n output lines. So in that situation, a minimum of one output prototype may be repeated for various input values. There are two kinds of higher-order decoders like 3 Line to 8 Line Decoder & 4 Line to 16 Line Decoder. This article discusses an overview of 3 Line to 8 Line Decoder A decoder is a combinational circuit constructed with logic gates. It is the reverse of the encoder. A decoder circuit is used to transform a set of digital input signals into an equivalent decimal code of its output. For 'n' inputs a decoder gives 2^n outputs. In this article, we will discuss on 4 to 16 decoder circuit design using 3 to 8.

4:2 Priority Encoder Truth Table: The next drawback can be avoided by giving priority to MSB bits, the Encoder will check from the MSB and once it finds the first bit that high (1) it will generate the output accordingly The truth table of this type of decoder is shown below. If the input to this decoder is 1000, then output Y8 will be low and all other outputs will be high as shown in figure. This will be so on for all the input combinations. From the above truth table, a 4-to-16 decoder can be implemented by using 4 NOT gates and 16 decoding NAND gates 4 to 16 decoder using 3 to 8 decoders,4 to 16 decoder using 3 to 8 decoder,4 to 16 decoder using 3 to 8 decoders in hindi,4 X 16 decoder using 3X 8 decoders,..

3. We want to design a circuit which will take four binary inputs and print hexadecimal number equivalent to that binary number. This circuit is called seven segment hex decoder. There are 16 digits in hexadecimal number which are 0-9 numbers and A-F alphabets. We will use common cathode display. See this table. 7-segment HEX decoder truth table
4. Circuit diagram, truth table and applications. Demultiplexer or Demux is a combinational circuit that distributes the single input data to a specific output line. The control inputs or selection lines are used to select a specific output line from the possible output lines. Demultiplexer works opposite to that of the multiplexer  ### Encoder Logic Diagram With Truth Table - Wiring Diagram

1. Can anyone show me how to make a 4 x 16 decoder from 2 3 x 8 decoders. I need very basic info (truth tables and basic gates). Thanks, any and all info is appreciated. If you could explain what the output of the gate is that would be helpful too
2. J.J. Shann 4-15 4-3 Decoder n-bit binary code: — is capable of representing up to 2n distinct elements of coded information. Decoding: — the conversion of an n-bit input code to an m-bit output code w/ n ≤m ≤2n s.t. each valid input code word produces a unique output code. Decoder: — a combinational ckt w/ an n-bit binary code applied to its.
3. BCD Circuit. This IC circuit is used to convert 4-bit BCD code to Decimal using the circuit shown. The schematic shows a 4-bit converter circuit, because BCD only uses 4-bits. There are nine bits on the output because decimal counts from zero to nine. The true table for the BCD to Decimal Decoder is shown above

5. BCD-to-7segment decoder 1. Use data sheet to draw the schematic (pin diagram) of the 7448 a BCD-to-7segment decoder and write down its function table. Multiplexer 2. Design a 2 to one multiplexer using NAND gates only. Write down truth table and Boolean expression for the output. Draw the circuit connection in both logic diagram and pin diagram An alternate circuit for the 2-to-4 line decoder is: Replacing the 1-to-2 Decoders with their circuits will show that both circuits are equivalent. In a similar fashion a 3-to-8 line decoder can be made from a 1-to-2 line decoder and a 2-to-4 line decoder, and a 4-to-16 line decoder can be made from two 2-to-4 line decoders Truth Table: DLD 7-segment Display Truth Table. From here we can get minimized expressions for a, b, c, d, e, f, g using K-MAP. Here we only need value 0 though 9. Priority encoders can be easily connected in arrays to make larger encoders, such as one 16-to-4 encoder made from six 4-to-2 priority encoders - four 4-to-2 encoders having the signal source connected to their inputs, and the two remaining encoders take the output of the first four as input
