Functional Description
The HD74AC153 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 HD74AC153 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.
