DESCRIPTION

The M54/74HC151 is a high speed CMOS 8 CHAN-

NEL MULTIPLEXER fabricated in silicon gate

C2MOS technology. It has the same high speed per-

formance of LSTTL combined with true CMOS low

power consumption. It provides, in one package, the

ability to select one bit of data from up to eight

sources. The HC151 can be used as a universal

function generator to generate any logic function of

four variables. Outputs Y and W are complementary

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.
