A 1 to 8 demultiplexer with data input Din, address inputs S0, S1, and S2, (with S0  as the LSB) and Y̅0 to Y̅ 7 as the eight de-multiplexed output, is to be designed using two 2 to 4 decoders (with enable input E and address input A0 and A1) as shown in the figure. Din, S0, S1, and S2 are to be connected to P, Q, R, and S but not necessarily in this order. The respective input connections to P, Q, R, and S terminals should be
  • a)
    S2, Din, S0,  and S1
  • b)
    S1, Din,, S0,  and S2
  • c)
    Din,, S0, S1, and S2
  • d)
    Din, S2, S0, and S1
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
A 1 to 8 demultiplexer with data input Din,address inputs S0, S1, and ...
The given question is the expansion of
2 : 4 decoder to  1 : 8 decoder 
We need to implement 1 : 8 DEMUX.
So, select lines of De-Mux should be mapped to address lines of the decoder.
The LSB of De-Mux should be connected to the LSB of address lines of the decoder
∴ R → S0 
and S→ S1
Input to both the decoder should be same so
∴ P → Din
∴ NOT gate along with OR gate in case to select one decoder at a time so Q → S2 
So,
P → Din
Q → S2
R → S
S→ S1
Hence option (D) is correct
