What is 8-input 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 do you implement an 8 to 1 multiplexer?
All you need to do is connect the eight inputs to GND (Ground) or VDD to match the 0s and 1s of the Q output of the truth table. What this tells us is that the CD4512 is an 8:1 multiplexer. The three selection inputs, A, B, and C are used to select one of the eight D0 to D7 data inputs.
What is ic74151?
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 select lines does a multiplexer with 8 data inputs have?
3 selection lines
We know that 8×1 Multiplexer has 8 data inputs, 3 selection lines and one output.
What is the logic function for a 8 1 MUX?
The given function is in terms of minterms and is to be implemented using a 8:1 MUX. An 8:1 MUX has three select lines, whereas the given function is a 4 variable function. Hence a logic is needed to give combination of A as inputs while only B, C and D as select line inputs.
How many 2 way multiplexors are needed to build a 8 way multiplexor?
Whereas, 8×1 Multiplexer has 8 data inputs, 3 selection lines and one output. So, we require two 4×1 Multiplexers in first stage in order to get the 8 data inputs.
How many data lines are needed for 8 inputs?
three data select lines
For selecting eight inputs, there are three data select lines that must be used. The multiplexer requires the data select lines.
How many selected lines would be required for an 8 line to 1 line multiplexer?
3
An 8 × 1 multiplexer selects one of the 8 inputs and presents it to the output, i.e. So the number of select lines will be 3.
