The example which follows will clarify the procedure. To contact the author.

On the other hand, entry 3 on the level Htherefore is connected to the positive tension. How to make a site? Now let us carry the entry of validation to state 1: The integrated circuit 74LS contains two demultiplexers with 4 ways.

Moreover, the use of a multiplexer makes it possible to pass easily from a switching function to another by changing the level of the inputs.

This is made possible because the equation of the exit of a multiplexer reveals all the possible combinations of the entries of order. According to what was known as before, the four switches are connected to the four entries of order D, C, B, A of the multiplexer.

Dynamic page of welcome. This one, carried to the state 1force the exit of the multiplexer corresponding to state 0 independently of the state of the other entries. The stitching and the logic diagram of this circuit are given on figure 41, while figure 42 gives its truth datawheet.

The stitching and the logic diagram of this integrated circuit are given on figure 32, while figure 33 gives its truth table.

The expressions and lead us to the logic diagram of figure In this chapter, we will examine the demultiplexers which are circuits whose function is opposite among that of the multiplexers.

Return to the synopsis. Since all the combinations of the entries A, B, C and D are present in this equation, we can fulfill with this multiplexer any switching function comprising the same number of entries, that is to say 4. Thus to use a decoder out of demultiplexer, the entry of validation becomes the 47153 and the entries of the decoder become the entries of ordering of the ddatasheet.

Otherwise, it is necessary to turn to the demultiplexer integrated into 4 ways: High of page Preceding page Following page. Click here for the datashwet lesson or in the synopsis envisaged to this end.

The not selected exits position with state 1. For each combination, one indicates the logical level that must take the exit. In the table of figure 35, the lines represented in red characters correspond if at least two of the entries of icc are on the level H and for which the exit must datxsheet be with the level H. It is noticed that the binary number formed by the state of the entries of selection B and A gives the decimal index of the exit concerned.

We know that the majority of the decoders datasheet their active exits at state 0 and their entry of active validation to state 0. If one has the integrated circuitone can carry out the circuit of figure Let us examine simplest of the demultiplexers, that with 2 ways. The integrated circuit contains two multiplexers with 4 ways at entries of selection A and B communes. This one indeed requires at dwtasheet three integrated circuits: Datassheet exit of the circuit is brought to the level H when at least two of the reversers are commutated on the positive tension.

One realizes that it is necessary to employ several types of doors, of the doors OR with 3 entriesa door OR at 2 entries and a door AND 4 entries.

Use of a decoder out of demultiplexer. Form of the perso pages. The next theory will 47153 memories. For each combination of the entries of order, one defers in the column of the exit the state that this one must take. To know how to position the other entries, one draws up a table with all the combinations of the entries of order. The advantage of the multiplexer compared to the network of doors is obvious: Information, present on the input, is acicular towards the exit selected by the state of the entries of order.

Static page of welcome. Electronic forum and Infos. The exit S with for the equation: The diagram symbolic datasneet and the mechanical equivalent of a demultiplexer with 2 ways are presented at figure A circuit of this kind can be used for the indication of breakdowns, or for the counting of parts on a production line.

The two groupings and D give us the following equation of S1: Figure 43 illustrates how one passes from a decoder to a demultiplexer. The data present in D is acicular towards S0 or S1 depending on the state of the 741533 of order A.
