Functional Description
The ’F153 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 ’F153 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 as
follows:

The ’F153 can be used to move data from a group of regis-
ters to a common output bus. The particular register from
which the data came would be determined by the state of
the Select inputs. A less obvious application is as a function
generator. The ’F153 can generate two functions of three
variables. This is useful for implementing highly irregular
random logic.
