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; DIP SOP TSSOP ORDER CODES PACKAGE TUBE DIP SOP TSSOP M74HC151B1R M74HC151M1R T&R M74HC151RM13TR M74HC151TTR 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.
