The M74HC151B1 is a high speed CMOS 8 channel multiplexer fabricated with silicon gate C2MOS technology. It provides, in one package, the ability to select one bit of data from up to eight sources. The M74HC151B1 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.
