How many output lines does a 4 input decoder have
Is the number of output lines for a decoder with 4 input lines?
In a decoder, if the input lines are 4 then number of maximum output lines will be: 2.
How many output lines does a 2 to 4 decoder have?
The 2-to-4 line binary decoder depicted above consists of an array of four AND gates. The 2 binary inputs labeled A and B are decoded into one of 4 outputs, hence the description of a 2-to-4 binary decoder. Each output represents one of the minterms of the 2 input variables, (each output = a minterm).
How many input and output does a decoder need?
The name “Decoder” means to translate or decode coded information from one format into another, so a binary decoder transforms “n” binary input signals into an equivalent code using 2n outputs.
How many outputs does a 3 input decoder have?
eight outputs
This decoder circuit gives 8 logic outputs for 3 inputs and has a enable pin. The circuit is designed with AND and NAND logic gates. It takes 3 binary inputs and activates one of the eight outputs. 3 to 8 line decoder circuit is also called a binary to an octal decoder.
How many outputs does a decoder have?
Decoder is a combinational circuit that has ‘n’ input lines and maximum of 2n output lines. One of these outputs will be active High based on the combination of inputs present, when the decoder is enabled.
How many 2 to 4 line decoders with an enable input are needed to construct a 4 to 16 line decoder without using any other logic gates?
Four 2*4 encoders are required to produce 16 outputs and 1 extra 2*4 decoder is required to enable the decoder when creating 4*16 decoders.

How many lines will a 8 input decoder have?
So, a two-to-four decoder will have two input lines and four output lines, while a three-to-eight decoder will have three input lines and eight output lines.
What is decoder explain 3 to 8 line decoder?
3 to 8 line decoder:
The 3 to 8 line decoder is also known as Binary to Octal Decoder. In a 3 to 8 line decoder, there is a total of eight outputs, i.e., Y0, Y1, Y2, Y3, Y4, Y5, Y6, and Y7 and three outputs, i.e., A0, A1, and A2. This circuit has an enable input ‘E’.
What is the difference between 3/8 decoder and 4/16 decoder?
A decoder circuit of the higher combination is obtained by adding two or more lower combinational circuits. 4 to 16 decoder circuit is obtained from two 3 to 8 decoder circuits or three 2 to 4 decoder circuits. When two 3 to 8 Decoder circuits are combined the enable pin acts as the input for both the decoders.
How many inputs are needed for a 16 decoder?
16 = 24 = 2n. Thus, number of inputs is 4.
How many 3 to 8 line decoders with an enable input are needed to construct a 6?
How many 3-to-8 line decoders with an enable input are needed to construct a 6-to-64 line decoder without using any other logic gates? hence required decoders (from fig.) = 9 so ans is ( C) part.
What is a 4 line to 16 line decoder?
General description. The 74HC154; 74HCT154 is a 4-to-16 line decoder/demultiplexer. It decodes four binary weighted address inputs (A0 to A3) to sixteen mutually exclusive outputs (Y0 to Y15). The device features two input enable (E0 and E1) inputs. A HIGH on either of the input enables forces the outputs HIGH.
What is a 4/16 decoder?
A 4-to-16 decoder consists of 4 inputs and 16 outputs. Similar to all the decoders discussed above, in this also only one output will be low at a given time and all other outputs are high (using maxterms). The truth table of this type of decoder is shown below.
What is 4-bit decoder?
A 4-bit decoder has 4 input lines and 16 output lines. That is 16 decoding gates are required to decode all possible combinations of four bits. For any given code on its input, one of the sixteen output becomes HIGH. Advertisements. Binary codes corresponding outputs and decoding functions are described in the table.
How many outputs does a 4/16 decoder have?
4-to-16 Line Decoder/Demultiplexer DIP-24 0.6″W
The 74HCT154 is a 4-to-16 line decoder/demultiplexer and decodes four binary weighted address inputs (A0 to A3) to sixteen mutually exclusive outputs (Y0 to Y15). The device features two input enable (E0 and E1) inputs.
What is a decoder circuit?
A decoder is a circuit that changes a code into a set of signals. 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.
How many decoders are there?
There are different types of decoders like 4, 8, and 16 decoders and the truth table of decoder depends upon a particular decoder chosen by the user. The subsequent description is about a 4-bit decoder and its truth table.
