From the following list of input conditions, determine the state of the five output leads on a 74148 octal-to-binary encoder.
I0 = 1 I3 = 1 I6 = 1
I1 = 1 I4 = 0 I7 = 1
I2 = 1 I5 = 1 EI = 0
GS = L, A0 = L, A1 = L, A2 = H, EO = H
GS = L, A0 = H, A1 = L, A2 = L, EO = H
GS = L, A0 = L, A1 = H, A2 = L, EO = H
GS = L, A0 = H, A1 = H, A2 = L, EO = H
