74HC151 is 8 - Input Multiplexer 16 Pin IC. Data Selector/Multiplexer contains full on-chip decoding to select one-of-eight data sources as a result of a unique three binary code at select inputs. Two complementary outputs provide both inverting and non-inverting buffer operation. A Strobe input is provided which, when at  high level, disables all data inputs and forces Y output to low state and W output to high state. Select input buffers incorporate internal overlap features to ensure that select input changes do not cause invalid output transients.Used for Boolean Function Generator.
