FUNCTIONAL DESCRIPTION
The MC74AC153/74ACT153 is a dual 4
input
multiplexer. It can select two bits of data from up to four
sources under the control of the common Select inputs (S
0
,
S
1
). The two 4
input multiplexer circuits have individual
active
LOW Enables (E
a
,E
b
) which can be used to strobe
the outputs independently. When the Enables (E
a
, E
b
) are
HIGH, the corresponding outputs (Z
a
, Z
b
) are forced LOW.
The MC74AC153/74ACT153 is the logic implementation
of a 2
pole, 4
position switch, where the position of the
switch is determined by the logic levels supplied to the two
Select inputs. The logic equations for the outputs are shown
below.
