It provides, in one package, the ability to select one bit of data from up to eight sources. The M74HC151 can be used as a universal function generator to generate any logic function of four variables. Outputs Y and W are complementary; the selection depends on the address inputs A, B, and C. The strobe input must be taken low to enable this device, when the strobe is high W output is forced high and consequently Y output goes low. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
