When the active-Low enable (G) is Low, the X74_151 multiplexer chooses one data bit from eight sources (D7 - D0) under control of the select inputs A, B, and C. The output (Y) reflects the state of the selected input, and the active-Low output (W) reflects the inverse of the selected input as shown in the truth table. When G is High, the Y output is Low, and the W output is High.
