These monolithic data selectors/multiplexers contain full on-chip binary decoding to select the desired data source. The DM74S151N selects one-of-eight data sources. They have a strobe input which must be at a low logic level to enable these devices. A high level at the strobe forces the W output high, and the Y output (as applicable) low. The DM74S151N feature complementary W and Y outputs.
