Multiple choice

The following binary values were applied to the X and Y inputs of the NAND latch shown in the figure in the sequence indicated below: X = 0, Y = 1; X = 0, Y = 0; X = 1, Y = 1. The corresponding stable P, Q outputs will be

  1. P = 1, Q = 0; P = 1, Q = 0; P = 1, Q = 0 or P = 0, Q = 1

  2. P = 1, Q = 0; P = 0, Q = 1; or P = 0, Q = 1; P = 0, Q = 1

  3. P = 1, Q = 0; P = 1, Q = 1; P = 1, Q = 0 or P = 0, Q = 1

  4. P = 1, Q = 0; P = 1, Q = 1; P = 1, Q = 1
