Question
For the MUX shown here, let all D inputs be 1001, both S inputs be HIGH, and the EN input be HIGH. What will be the status of the Y output?Select one:a.Don't careb.HIGHc.LOWd.High Impedance
Solution
To determine the status of the Y output for the given MUX configuration, we need to analyze the inputs and the truth table of the MUX.
The MUX has two select inputs, S1 and S0, and four data inputs, D0, D1, D2, and D3. The EN input is used to enable or disable the MUX.
In this case, both S inputs are set to HIGH, which means S1 = 1 and S0 = 1. The D inputs are set to 1001, which means D3 = 1, D2 = 0, D1 = 0, and D0 = 1. The EN input is set to HIGH, indicating that the MUX is enabled.
Now, let's refer to the truth table of a 4:1 MUX to determine the output based on the inputs:
S1 | S0 | D0 | D1 | D2 | D3 | Y
1 | 1 | D0 | D1 | D2 | D3 | ?
Since S1 = 1 and S0 = 1, the output Y will be equal to D3, which is 1 in this case.
Therefore, the status of the Y output will be HIGH.
