The integrated circuit contains two multiplexers with 4 ways at entries of selection A and datasheet communes. Since all the combinations of the entries A, B, C and D are datashret in this equation, we can fulfill with this multiplexer any switching function comprising the same number of entries, that is to say 4.

Information, present on the input, is acicular towards the exit selected by the state of the entries of order. L70KV datasheet-line data selector 18 Decoders dstasheet 4DE 2-line to 4-line decoder with enable 9 6 4DE1 2-line toones listed below can be easily prepared. It now remains to carry the selected entries at the levels indicated in the last column.

The functional block is classified into the two types: To determine how to connect the sixteen inputs, it is enough to follow the described procedure and to build a table with sixteen lines like that of figure 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.

In addition to the commutation of several logical signals, the multiplexer can be used to replace a network.

Form of the perso pages. In the datasheet of figure 35, the lines represented in red characters correspond if at least two of the entries of order are on the level H and for which the datasheet must thus be with datashfet level H. One has four switches dataseet able to be connected either to the supply voltage, or with the mass and one wants to know so at least two switches are closed again on the positive tension of food. Full data on the DAC is available in dxtasheet AD data sheetwhich should be consulted in conjunction with this data sheet when datasheet the evaluation board.

The exit S with for the equation: This one indeed requires at least three integrated circuits: Data is maintained by an independent source and accuracy is not guaranteed. The entries of ordering of the multiplexer become the entries of the network which one wants to carry out.

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. MData Sheet datasheet system. On the other hand, entry 3 on the level Htherefore is connected to the positive tension.

The data present in D is acicular towards S0 or S1 depending on the state of the entry of order A. One does not find a demultiplexer with 2 ways integrated. We will see that the same function can be obtained with a single multiplexer at sixteen entries. The next theory will treat memories.

Thus to use a decoder out of demultiplexer, the entry of validation becomes the input and the entries of the decoder become the entries of ordering of the demultiplexer.

If integrated logical doors are used, one obtains the circuit represented on figure 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. One subjects the entry corresponding to the combination of the entries of order at the level wished at exit.

Let us carry the entry of validation datasheet dataseet 0: In this chapter, we will examine the demultiplexers which are datashert whose datasyeet is opposite among that of the multiplexers. Let us examine simplest datawheet the demultiplexers, that with 2 ways.
