DM74S151
Description
These data selectors/multiplexers contain full on-chip decoding to select the desired data source. The DM74S151 selects one-of-eight data sources. The DM74S151 has 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 LOW.
The DM74S151 features plementary W and Y outputs.
