Functional Description
The 74F352 is a dual 4-input multiplexer. It selects 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 HIGH. The logic equations for the outputs
are shown below:

The 74F352 can be used to move data from a group of reg-
isters 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 func-
tion generator. The 74F352 can generate two functions of
three variables. This is useful for implementing highly irreg-
ular random logic.
