How many 2X4 decoders are needed to draw a 4X16 decoder?

Update: you need 5 decoders.

How many 4 to 16 decoders are needed to implement an 8 to 256 decoder note all the decoders have an enable input?

The number of 4 line to-16 line decoders required to make an 8-line-to-256 line decoder is. Correct answer is ’17’. Can you explain this answer?

What is the least number of decoders minimum possible hardware required for designing 6 64 decoder?

For 64 outputs eight 3 to 8 decoders are required and to address (or select) each of them one more 3 to 8 decoders is required. The scheme to implement 6 to 64 decoders using nine 3 to 8 decoders is explained below. Hope it helps.

What is 2×4 decoder?

2-to-4 Binary Decoder – 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). The output values will be: Qo=A’B’

How many inputs are required for a 4 16 decoder?

4 to 16 Decoder Substitute, m1 = 8 and m2 = 16 in the above formula. Therefore, we require two 3 to 8 decoders for implementing one 4 to 16 decoder. The block diagram of 4 to 16 decoder using 3 to 8 decoders is shown in the following figure. The parallel inputs A2, A1 & A0 are applied to each 3 to 8 decoder.

How many inputs are needed for a 16 decoder?

Explanation: A binary decoder is a combinational logic circuit which decodes binary information from n-inputs to a maximum of 2n outputs. Here, number of outputs = 16. 16 = 24 = 2n. Thus, number of inputs is 4.

How many inputs are required for a 4 to 16 decoder?

A 4×16 decoder has 4 inputs and 16 outputs, with the outputs going high for the corresponding 4-bit input. Similar is the case of a 2×4 decoder except for its 2 inputs and 4 outputs.

What will be the maximum number of outputs for a decoder with a 6 bit data word?

How many possible outputs would a decoder have with a 6-bit binary input? Explanation: The possible outputs would be: 2n = 64 (Since n = 6 here). 7.

How many outputs does a decoder with 4 inputs have?

16 outputs
Similarly, a 4-to-16 line decoder activates one of 16 outputs for each 4-bit input in the integer range [0,15]. A BCD to decimal decoder has ten output bits.

Can you implement a code converter with encoder and decoder?

Decoder and encoder circuits are used to convert from one type of input encoding to a different output encoding. There are many other possible types of code converters known as BCD-to-seven-segment code converter, BCD-to-Gray code converter, BCD-to-excess-3 code converters, and so on.

How to make a 6×64 with 4×16 decoders?

You can use one 2X4 decoder and four 4X16 decoders to make a 6X64 . Basically start with 2 of the 6 inputs for the 2X4 decoder. The 4 outputs will drive the enable pin of the four 4X16. And the remaining 4 of the 6 inputs will be the 4 inputs for all four 4X16.

How many decoders are required to handle 64 outputs?

All the best. this can be solve easily with the given formula. For 64 outputs eight 3 to 8 decoders are required and to address (or select) each of them one more 3 to 8 decoders is required. The scheme to implement 6 to 64 decoders using nine 3 to 8 decoders is explained below.

What is a decoder circuit design?

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 decoder.

How do I implement a 6:64 decoder in Logicworks?

Show how to implement a 6:64 decoder using smaller decoder parts. Implement your design in LogicWorks using the decoder parts in the 7400.clf library. Make sure your file is ready to simulate to show your decoder works properly.
