Code Converters and Multiplexers
For the following conditions on a 7485 magnitude comparator, what will be the state of each of the three outputs? A0 = 0 B0 = 1 IA < B = 0 A1 = 1 B1 = 0 IA = B = 1 A2 = 1 B2 = 0 IA > B = 0 A3 = 0 B3 = 0
A = B = 0, A < B = 0, A > B = 1
A = B = 0, A < B = 1, A > B = 0
A = B = 1, A < B = 0, A > B = 0
A = B = 0, A < B = 0, A > B = 0
Correct Answer:
A = B = 0, A < B = 0, A > B = 1
