When the active-Low enable input (G) is Low, the X74_150 multiplexer chooses one data bit from 16 sources (E15 - E0) under the control of select inputs A, B, C, and D. The active-Low output (W) reflects the inverse of the selected input, as shown in the truth table. When the enable input (G) is High, the output (W) is High.
