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.
