How many and gates are required for a 1 to 16 multiplexer?
Whereas, 16×1 Multiplexer has 16 data inputs, 4 selection lines and one output. So, we require two 8×1 Multiplexers in first stage in order to get the 16 data inputs.
What is a 16 bit MUX?
description. The SN74CBT16233 is a 16-bit 1-of-2 FET multiplexer/demultiplexer used in applications in which two separate data paths must be multiplexed onto, or demultiplexed from, a single path. This device can be used for memory interleaving, where two different banks of memory need to be addressed simultaneously.
What is the data input of 16 1 MUX?
16 to 1 Multiplexer The 2×1 multiplexer has only 1 selection line. For getting 16 data inputs, we need two 8 ×1 multiplexers. The 8×1 multiplexer produces one output. So, in order to get the final output, we need a 2×1 multiplexer.
What is 8×1 multiplexer?
An 8-to-1 multiplexer consists of eight data inputs D0 through D7, three input select lines S0 through S2 and a single output line Y. Depending on the select lines combinations, multiplexer selects the inputs.
How many inputs are needed for a 1/16 decoder?
16 = 24 = 2n. Thus, number of inputs is 4.
How many selection lines are required to design a 1/16 demultiplexer?
So the number of select lines will be 4.
What is select lines in multiplexer?
A multiplexer (mux) or a data selector or input selector is a combinational circuit device that selects one of N inputs and provides it on its output. A set of inputs called select lines determine which input should be passed to the output. For a 2:1 (two-to-one) MUX, when sel is 0, q = a and when sel is 1, q = b.
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.
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 IC 74151?
74HC151 is 8 – Input Multiplexer 16 Pin IC. Data Selector/Multiplexer contains full on-chip decoding to select one-of-eight data sources as a result of a unique three binary code at select inputs. Two complementary outputs provide both inverting and non-inverting buffer operation.
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)

What is multiplexer in gate?
Multiplexers are mainly used to increase amount of the data that can be sent over the network within certain amount of time and bandwidth. Attention reader! Don’t stop learning now. Practice GATE exam well before the actual exam with the subject-wise and overall quizzes available in GATE Test Series Course.
How to implement or gate using 2 1 MUX?
c) Implementation of OR gate using 2 : 1 Mux using “n-1” selection lines. Implementation of NAND, NOR, XOR and XNOR gates requires two 2:1 Mux. First multiplexer will act as NOT gate which will provide complemented input to the second multiplexer.
What is a multiplexer of inputs?
A multiplexer of inputs has select lines, which are used to select which input line to send to the output. [2] A multiplexer makes it possible for several input signals to share one device or resource, for example, one analog-to-digital converter or one communications transmission medium , instead of having one device per input signal.
How many gates does a 2-to-1 multiplexer need?
Which can be expressed as a truth table : Or, in simpler notation: . A straightforward realization of this 2-to-1 multiplexer would need 2 AND gates, an OR gate, and a NOT gate. While this is mathematically correct, a direct physical implementation would be prone to race conditions that require additional gates to suppress. inputs.
