Consider the following circuit diagram
A 4-bit subtractor, four 4-bit three-state buffers (with bus input and output), and one inverter is used to subtract two numbers (Y - X),  X = 0101 and Y = 0010
If A = 0, then D and Bout are respectively
  • a)
    0011 and 0
  • b)
    1101 and 0
  • c)
    0011 and 1
  • d)
    1101 and 1
Correct answer is option 'D'. Can you explain this answer?

Concept:
The truth table for a tristate buffer is as shown:

Observation:
If the “Enable” input signal is 1, the input is simply passed to the output.
If the “Enable” input signal is 0, the tristate buffer passes a high impedance signal that disconnects its output from the circuit.
Application:
When A = 0, Buffer 1 and Buffer 3 are enabled, and buffer 2 and 4 are disabled.
The input to the 4-bit subtractor will be Y and X respectively, such that the output is:
D = Y – X = 0010 – 0101
= 1101 with a borrow of 1, i.e. Bout = 1
