DESCRIPTION
The M74HC151 is an 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
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.

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC
