parallel to serial converter using mux and flipflops

It is used as a digital switch, parallel to serial converter, for multiplexing signals in TDM and many more purposes. Where, S2, S1, S0 are the selection inputs,Īnd, I0, I1, I2, I3, I4, I5, I6, I7 are the input lines.Ī multiplexer is a very important component of electronics. The truth table of an 8:1 MUX is given below: S2 Block diagram of an 8:1 MUX is given below: Here 2 n is the number of inputs, 1 denotes the number of outputs and n is the number of selection line. Multiplexers are expressed as 2 n:1 multiplexer such as 2:1 MUX, 4:1 MUX, 8:1 MUX, 16:1 MUX etc. If a MUX has 2 n number of input lines then it must have n number of selection line pins, i.e., if a MUX has 8 = 2 3 number of input pins then it must have 3 selection lines. It is used to switch the value of the output from one input value to another depending on the value of selection inputs. Demultiplexer acts as a signal allocator.Ī multiplexer is used for multiplexing purposes, in communication schemes such as TDM, in parallel to serial converter, etc.Ī demultiplexer is used for demultiplexing purposes, in communication schemes such as TDM, in serial to parallel converter, etc.Ī multiplexer, also known as MUX is a combinational circuit element that is used to choose one among many inputs as its only output depending on the input given to the selection line. Purpose Multiplexer acts as a digital switch. If a demultiplexer has n number of selection lines then it will have 2 n number of output lines or vice versa. If a multiplexer has 2 n number of input lines then it will have n number of selection lines or vice versa. It has only one input pin apart from selection lines. The demultiplexer is a combinational circuit element that is used to channel the input to one of the many output lines depending on the input(s) of the selection line(s). The multiplexer is a combinational circuit element that chooses one out of many inputs as output depending on the input(s) of selection line(s) Difference between Multiplexer and Demultiplexer in tabular form Multiplexer In this article, we will discuss the difference between multiplexer and demultiplexer. Multiplexer and Demultiplexer are two combinational circuit elements.
