When the active-Low enable inputs G1 and G2 are Low, the data output Y1, reflects the data input chosen by select inputs A and B from data inputs I1C3 - I1C0. The data output Y2 reflects the data input chosen by select inputs A and B from data inputs I2C3 - I2C0. When G1 or G2 is High, the corresponding output, Y1 or Y2 respectively, is Low.
