1 16 Demultiplexer

In 1×16 de-multiplexer, there are total of 16 outputs, i.e., Y0, Y1, …, Y16, 4 selection lines, i.e., S0, S1, S2, and S3 and single input, i.e., A. On the basis of the combination of inputs which are present at the selection lines S0, S1, and S2, the input will be connected to one of these outputs.

How does a 1 to 16 demultiplexer work?

1 to 16 demultiplexer has one input data, four select lines A, B, C and D and 16 output lines Y0 to Y15. This is implemented using AND and NOT gate. 1 to 16 demultiplexer is implemented using the logic circuit below. This can be implemented using 1 to 8 demultiplexer, 1 to 4 demultiplexer and 1 to 2 demultiplexer.

What is a 1/4 demultiplexer?

A 1-to-4 demultiplexer has a single input (D), two selection lines (S1 and S0) and four outputs (Y0 to Y3). The input data goes to any one of the four outputs at a given time for a particular combination of select lines.

How many 1/4 demux are needed to implement a 1/16 demux?

A 16 × 1 multiplexer has 16 inputs so if we use 4 × 1 multiplexers: At first stage: 4 multiplexers are needed for 16 inputs, At second stage: the output of these 4 multiplexers is connected to inputs of 1 multiplexer. Total 4 × 1 multiplexers needed are 4 + 1 = 5.

How many inputs are required for a 1-of-16?

How many inputs are required for a 1-of-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.

What is a 1-of-16 decoder?

The HEF4515B is a 1-of-16 decoder/demultiplexer, having four binary weighted address inputs (A0 to A3), a latch enable input (EL), and an active LOW enable input (E). The 16 outputs (O0 to O15) are mutually exclusive active LOW. When EL is HIGH, the selected output is determined by the data on An.

Why is demultiplexer used?

Demultiplexer is used to connect a single source to multiple destinations. The main application area of demultiplexer is communication system, where multiplexers are used. Most of the communication system are bidirectional i.e., they function in both ways (transmitting and receiving signals).

Which IC is used for 1 to 16 demux?

The IC 74 × 154 is used as a 1 to 16 De-multiplexer.

What is the principle of demultiplexer?

The demultiplexer takes one single input data line and then switches it to any one of a number of individual output lines one at a time. The demultiplexer converts a serial data signal at the input to a parallel data at its output lines as shown below.

How is demultiplexer calculated?

If s3 is zero, then one of the eight outputs of lower 1x8 De-Multiplexer will be equal to input, I based on the values of selection lines s2, s1 & s0. Similarly, if s3 is one, then one of the 8 outputs of upper 1x8 De-Multiplexer will be equal to input, I based on the values of selection lines s2, s1 & s0.

What are types of demultiplexer?

The different types of demultiplexers are 1-8 Demux, 1-16 Demux, 1-32 Demux. In demultiplexer, the selection of output line can be controlled through n-selection lines bit values.

What is a 2x1 multiplexer?

A 2-to-1 multiplexer consists of two inputs D0 and D1, one select input S and one output Y. Depending on the select signal, the output is connected to either of the inputs. Since there are two input signals, only two ways are possible to connect the inputs to the outputs, so one select is needed to do these operations.

How many inputs does a 16 1 multiplexer have?

The SY10/100E164 are 16:1 multiplexers with a differential output. The select inputs (SEL0,1,2,3) control which one of the sixteen data inputs (A0–A15) is propagated to the output. Special attention to the design layout results in a typical skew between the 16 inputs of only 50ps.

How do you make a 16 1 MUX using 4 1 mux?

The basis: See it this way: You need a combinational logic with 16 input pins, 4 select lines and one output. In a 4:1 mux, you have 4 input pins, two select lines and one output. So, at the least you have to use 4 4:1 MUX, to obtain 16 input lines.

How many demultiplexers are there in IC 74155?

IC 74155 is a dual 1:4 line demultiplexer with individual strobe inputs. It has common binary address inputs (A, B and C) and it is available in single 16 pin package.

How many 1/16 decoder are required for decoding a 7 bit binary number?

7 bit means 2^7 combinations i.e 128. So to decode 128 combinations we require 128/16=8 1 of 16 decoders.

How many two input mixes are needed to create a 16 input?

Start with 8 2:1 mux to get 16 inputs, 8 outputs, one control.

Can 1 output have 2 inputs?

(Input) Family Member's name	(Output) Family Member's Age
Marcos	11
Esther	46
Samuel	47
Nina	47

What is a 4 to 16 decoder?

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.

Which type of decoder will select one sixteen outputs?

It is given as 16 outputs and 4 input i.e. 4*16 decoder. As binary is 0 and 1. So obviously it's hexadecimal decoder.
