General Description

This data selector/multiplexer contains full on-chip decoding to select the desired data source. The DM74LS151 selects one-of-eight data sources. The DM74LS151 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 out put HIGH, and the Y output LOW. The DM74LS151 features complementary W and Y outputs.
