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: In the table 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 exit must thus be with the level H. Dynamic page of welcome.

In addition to datasheet 74ls operation, the LS can generate any two functions of datasheet 74ls variables. To contact the author. It can select two bits of data from up to four sources datasheet 74ls the control of the common Select Inputs Sq, Si.

In short, the logical data present on the entry of validation is acicular towards the exit selected by the entries of the decoder. If integrated logical doors are used, one obtains the circuit represented on figure It can select two bits of data from four sources.

IC 74LS pin diagram datasheet & applicatoin notes – Datasheet Archive

In addition to multiplexer datwsheet, the Datasheet 74ls can generate any two datasheet 74ls of three variables It can select two bits of data from four sources. The particular register from which the data came would be determined by the state of the Datasheet 74ls Inputs. Electronic forum and Poem. It can select two bits of data from up to four sources under the datashewt of the common Select Inputs Sq, Si.

High of page Preceding page Following page. A less obvious application is a function generator. 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.


This one indeed requires at least three integrated circuits: Let us examine simplest of the demultiplexers, that with 2 ways. The expressions and lead us to the logic diagram of figure We know that the majority of the decoders have their active exits at state 0 and their entry of datsaheet validation to state 0.

IC Datasheet: 74LS153

How to make a adtasheet In addition to multiplexer operation, the LS datasheet 74ls generate any two functions of three variables. The particular register from which the data came would be determined by the state of the Select Inputs.

Use of 74lz153 decoder out of demultiplexer. The next theory will treat memories. In addition to the commutation of several logical signals, the multiplexer can be used to replace a network. One has four switches being 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.

The advantage of the multiplexer compared to the network of doors is obvious: A circuit of this kind can be used for the indication of breakdowns, or for the counting of parts on a production line. The circuit which results from it is deferred on figure N datasheet 74ls to n 74lz153. N lines to n lines. The diagram symbolic system and the mechanical equivalent of a demultiplexer with 2 ways are presented at figure The exit S with for the equation: SCILLC products are not designed, intended, or authorized for use as components in systems intended for surgical implant into the body, or other applications datasheet 74ls to support or sustain life, 74ls for any other application in which the failure of the SCILLC product could create a situation where personal injury or datasheet 74ls may occur.

Now let us carry the entry of validation to state 1: It now remains to carry the selected entries at the levels indicated in the last column.


Static page of welcome. It is noticed that the datashwet number formed by the state of the entries of selection B and A gives the decimal index of the exit concerned.

Return to the synopsis. Let us carry the entry of validation to state 0: This is useful for implementing highly irregular random logic. Motorola makes no warranty, datasheet 74ls or guarantee regarding the suitability of datasheet 74ls products for any particular purpose, nor does Motorola assume any datasheet 74ls arising out of the application or use of any product or datasheet 74ls, and specifically disclaims any and all liability, datasheet 74ls without limitation consequential or incidental damages.

74LS Datasheet(PDF) – Fairchild Semiconductor

The integrated circuit contains two multiplexers with 4 ways at entries of selection A and B communes. Electronic forum and Infos. One does not find a demultiplexer with 2 ways integrated. June 7, admin 0 Comments.


If one has the integrated circuitone can carry out the circuit of figure The stitching and the logic diagram of this circuit are given on figure 41, while figure 42 gives its truth table. Information, present on the input, is datashert towards the exit selected by the state of the entries of order.

Not more ttian one datasheet 74ls should be shorted at a time, nor for more than 1 second. Buyer shall indemnify and hold SCILLC and its officers, employees, datasheet 74ls, affiliates, and distributors harmless against all claims, costs, damages, and expenses, and reasonable dtasheet fees arising out of, directly or indirectly any claim of personal injury datasheet 74ls death associated with such datasheet 74ls or unauthorized use, even if such claim alleges that SCILLC was negligent regarding the design or manufacture of the part.
