What is multiplexer explain working of 8 1 multiplexer How can 16 1 mux be designed using 8 1 MUX and or gate?
16×1 multiplexer using 8×1 and 2×1 multiplexer We can implement the 16×1 multiplexer using a lower order multiplexer. To implement the 8×1 multiplexer, we need two 8×1 multiplexers and one 2×1 multiplexer. The 8×1 multiplexer has 3 selection lines, 4 inputs, and 1 output. The 2×1 multiplexer has only 1 selection line.
How many not gates are required for the construction of a 16 to 1 multiplexer?
A 16 × 1 multiplexer has 16 inputs so if we use 4 × 1 multiplexers: At first stage: 4 multiplexers are needed for 16 inputs, At second stage: the output of these 4 multiplexers is connected to inputs of 1 multiplexer. Total 4 × 1 multiplexers needed are 4 + 1 = 5.
Which IC is used for the implementation of 1 to 16 demux?
IC 74154
Explanation: IC 74154 is used for the implementation of 1-to-16 DEMUX, whose output is inverted input.
What is multiplexer in digital system?
In electronics, a multiplexer (or mux; spelled sometimes as multiplexor), also known as a data selector, is a device that selects between several analog or digital input signals and forwards the selected input to a single output line. The selection is directed by a separate set of digital inputs known as select lines.
How does a 16 1 multiplexer work?
The SY10/100E164 are 16:1 multiplexers with a differential output. The select inputs (SEL0,1,2,3) control which one of the sixteen data inputs (A0–A15) is propagated to the output. Special attention to the design layout results in a typical skew between the 16 inputs of only 50ps.
How do you make a 16 1 multiplexer?
The basis: See it this way: You need a combinational logic with 16 input pins, 4 select lines and one output. In a 4:1 mux, you have 4 input pins, two select lines and one output. So, at the least you have to use 4 4:1 MUX, to obtain 16 input lines.
How many inputs are needed for a 1/16 decoder?
16 = 24 = 2n. Thus, number of inputs is 4.
What is enable pin in mux?
In general, enable pin in multiplexers, de multiplexer, decoder and encoder ensures the functioning of the hardware ie “enables” the function of the logic circuit.
Is used for the implementation of 1 to 16 demux whose output is inverted input?
Clarification: IC 74154 is used for the implementation of 1-to-16 DEMUX, whose output is inverted input.
How does a digital multiplexer work?
A digital multiplexer has digital input signals coming from multiple data-acquisition networks. The device transfers these input signals to a processing system, typically a microprocessor, which receives and processes the data, transmits it to the output devices, and controls the system as a whole.
How many 16 input OR gates are required to build a 4/16 decoder?
Following the steps we took in the lecture, we are supposed to build a 4×16 decoder. So here taking k to be 4, k is even, so we will have 2k so 24=16 AND gates & 2 decoders each of size 2k/2 so 22=4.
How many 1/16 decoders are required for decoding a 7 bit binary number?
7 bit means 2^7 combinations i.e 128. So to decode 128 combinations we require 128/16=8 1 of 16 decoders. What does 1 of 16 decoder means?…Discussion :: Combinational Logic Circuits – General Questions (Q. No. 12)

Which pin is multiplexed?
A number of the available pins can be used for multiple purposes other than general purpose input/output when needed. Such pins are referred to as multiplexed pins. For example, the UART pins are designated as UART, but are multiplexed so that you can designate and use them as GPIO pins when you want.
Why enable pin is used?
The enable pin of ON Semiconductor eFuses provides a number of features. With all eFuses, a transistor may be used to force the pin low to disable the output. In addition, it may be left floating if no control of the enable pin is required.
