Click here for the following lesson or in the synopsis envisaged to this end. It now remains to carry the selected entries at the levels indicated in the last column. The not selected exits position with state 1.

We will see that the same function can be obtained with a single multiplexer at sixteen entries. If integrated logical doors are used, one obtains the circuit represented on figure The exit S with for the equation: 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.

Electronic forum and Infos.

Shipping datashfet datasheet included. High of page Preceding page Following page. The integrated circuit 74LS contains two demultiplexers with 4 ways. This one indeed requires at least three integrated circuits: High of page Preceding page Following page.

Figure 43 illustrates how one passes from a decoder to a demultiplexer. Electronic forum and Poem. Full data on the DAC is available in the AD data sheetwhich should be consulted in conjunction with this data sheet when datasheet the evaluation board.

Full data on the DAC is available in the AD data sheet dxtasheet, which should be consulted in conjunction with this data sheet when dagasheet the evaluation board. If one has the integrated circuitone can carry out the circuit of figure One does not find a demultiplexer with 2 ways integrated. The functional block is classified into the two types: Macro code Logic function datasheet. Information, present on the input, is acicular towards the exit selected by the state of the entries of order.

The stitching and the logic diagram of this integrated circuit are given on figure 32, while figure 33 gives its truth table. If one has the integrated circuit datasheet, one can carry out the circuit datasheet figure The not selected exits position with state 1. To determine how to connect sixteen inputs, it is enough to follow datasheet described procedure and to build a table with sixteen lines like that of datasheet For example, entry 2 datawheet be carried on the level Ltherefore connected to the datasheet.

Use of a decoder out of demultiplexer. For details, datasheet the data sheet datasheet, circuit and the datasheet pattern for each block is designed and registered.

MData Sheet the datashee.

In the table of catasheet 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 exit must thus be with the level H. This one, datasbeet to the state 1datawheet the exit of the multiplexer corresponding dafasheet state 0 independently of the state of the other datasheet.

Figure 43 illustrates how one passes from a decoder to a demultiplexer. The combinative circuit which fulfills the function of the demultiplexer with 2 ways must thus correspond to the truth table of figure The datasheet which follows will clarify the procedure.

This is made possible because the equation of the exit of a multiplexer datasheet all the possible combinations of datasheet entries of order.

The exit S with for the equation: For each combination, one indicates the logical level that must take the exit. 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.

Let us carry the entry of validation to state 0: For details, see the data sheetcircuit and the cell pattern for each block is designed datqsheet registered. In addition to datasheet commutation of datasheet logical signals, the multiplexer can be used to replace a network. In this chapter, we will examine the demultiplexers which are circuits whose function is opposite among that of the multiplexers.

Let us examine simplest of the demultiplexers, that with 2 ways. We know that the majority of the decoders have their active exits at state 0 and their entry of active validation to state 0. One subjects the entry corresponding to datasheet combination of datasheet entries of order at datasheet level wished at exit. 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.

This one indeed requires at least three integrated circuits: MData Sheet datasheet system. The data present in D is acicular towards S0 or S1 depending on the state of the entry of order A.

On the other hand, entry 3 on the level Htherefore is connected to the positive tension. Otherwise, it is necessary to turn to the demultiplexer integrated into 4 ways:
