The demultiplexer is also called as data distributors as it requires one input, 3 selected lines and 8 outputs. The 16 outputs (O0 to O15) are mutually exclusive active LOW. 1-OF-8 DECODER/DEMULTIPLEXER (0) 2020.02.07: MCP2551 - CAN Transceiver (0) 2020.02.04: Posted by Dekal. If data bit (I2.0) is ON, input 1 (I0.0) OFF, input 3 (I0.2) OFF and input 2 (I0.1) is ON, Output 3 (Q0.2) will be ON. Where n= number of input selector line. We can also go the opposite way and use a multiplexer with more inputs than required as a smaller MUX. The SL74HC138 decodes a three-bit Address to one-of-eight active- Let us consider 1:4 Demultiplexer as shown in Fig.1 below where: D is the input, S0 and S1 are the control inputs, I0, I1, I2, I3 are the 4 output lines and the data is transmit… Problem Description. There are many other types like 1-to-2, 1-to-8, 1-to-16 demultiplexers etc. The multiple input enables allow parallel ex-pansion to a 1-of-24 decoder using just three LS138 devices or to a 1-of-32 And if the outputs are 8 in number it can be termed as 1:8 users. This IC gives inverted output except for Data input 2C pin(15) in case of 1 to 4 Demultiplexer. Details, circuits diagrams, schematic designs, truth tables and application of different kind of MUXES are as follow. Consider D as input data and Y0-Y7 as the 8 output channels and S0,S1,S2 as control signals. And then, we will … Abstract: An 8:1 multiplexer and 1:8 demultiplexer chip set composed of GaAs direct-coupled FET logic (DCFL) has been designed and fabricated.

If data bit (I2.0) is ON, input 1 (I0.0), input 2 (I0.1) ON and input 3 (I0.2) is OFF, Output 7 (Q0.6) will be ON. There are two configurations of making a 1 to 4 Demultiplexer using individual 1 to 2 Demultiplexers. If Data bit (I2.0) is ON and all inputs are OFF (I0.0=0, I0.1=0 and I0.2=0), Output 1 (Q0.0) will be ON. check the link for the pins detail foe 74ls138 1:8 demultiplexer Jameco sells 1 to 8 demultiplexer and more with a lifetime guarantee and same day shipping. Mux is a device That has 2^n Input Lines. If s 3 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 s 2 , … Truth Table. The circuits were designed with tree type architecture and used memory cell type flip-flop (MCFF) as a flip-flop. It can be active high or active low.

In Arithmetic logic unit (ALU), the output of ALU can be stored in storage unit (multiple registers) by using Demultiplexer. We depends on ad revenue to keep creating quality content for you to learn and enjoy for free. 8:1 and 16:1 Multiplexers Similar to the process we saw above, we can design an 8 to 1 multiplexer using 2:1 multiplexers, 16:1 MUX using 4:1 MUX, or 16:1 MUX using 8:1 multiplexer. If data bit (I2.0) is ON, input 1 (I0.0) OFF, input 2 (I0.1) OFF and input 3 (I0.2) is ON, Output 2 (Q0.1) will be ON. The multiple input enables. I 0, I 1, I 2, I 3, I­ 4, I 5, I 6, I 7 are the eight output bits, S 0, S 1 and S 2 are the control bits and input D.

For this application we used S7-1200 PLC and TIA portal software for programming. Save my name, email, and website in this browser for the next time I comment. Introduction An 8-to-1 multiplexer is a digital device that selects one of the eight inputs lines to the output line by using three-bit selection line.The block diagram of 8-to-1 Mux is shown in Figure 1. 74155 IC is a Decoder/Demultiplexer IC which can be used as a 2-4 decoder or 3-8 decoder or 1-4 Demultiplexer or 1-8 Demultiplexer. There is also an Enable bit used for enabling or disabling the circuit. Thus, demultiplexers play a crucial role in the communication system. There is no need for a separate data line to each of the registers, a single Demux can store data in all connected registers. anyone can help on that please ?!!! Demultiplexers can be used to implement general purpose logic. Thus, depending on the number of the outputs the demultiplexer is termed. This DeMux can direct one data line onto 8 separate output channels and these 8 channels are controlled by 3 control signals. Accept Read More, PLC Selective Execution of the Application, PLC Selective Execution of a Application This is PLC Program for selective execution of the application. so this Demux has 4 output channels and to control 4 channel it needs 2 control signals. Output is inverted input 74159 CD4514/15 1:16 demux. A digital device capable of forwarding its single input onto any one of the output lines is called Demultiplexer abbreviated for DEMUX. The relation between the number of output lines and the number of select lines is the same as we saw in a … It can convert a serial data signal into parallel data signals thus it can be used as serial to parallel converter. 74LS138 1-To-8 Decoder/Demultiplexer IC – Datasheet. How many select lines are required for a 1-to-8 demultiplexer? It can be used as 1 to 8 Demultiplexer if pin (1) and Pin (15) are combined together to form Control signal C. and combine Strobe pin (2) and Pin(14) to use as Data input. Output is open collector and same as input 한잠, MPEG Demux를 사용한 제품을 게발을 했었고, 아직도 하는데, 요즘은 시들시들해서리 주절주절. the direction of a port as input, output or inout. Hence, [1:0] states that the port named as A is a vector with MSB = 1 and LSB = 0.
