74F352
Dual 4-Input Multiplexer
General Description
The 74F352 is a very high-speed dual 4-input multiplexer
with common Select inputs and individual Enable inputs for
each section. It can select two bits of data from four
sources. The two buffered outputs present data in the
inverted (complementary) form. The 74F352 is the func-
tional equivalent of the 74F153 except with inverted out-
puts.

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 (S0, S1). The two 4-input multiplexer
circuits have individual active LOW Enables (Ea, Eb) which
can be used to strobe the outputs independently. When the
Enables (Ea, Eb) are HIGH, the corresponding outputs (Za,
Zb) are forced HIGH. The logic equations for the outputs
are shown below:
Za = Ea • (I0a • S1 • S0 + I1a • S1• S0 +
I2a • S1 • S0 + I3a • S1 • S0)
Zb = Eb • (I0b • S1 • S0 + I1b • S1• S0 +
I2b • S1 • S0 + I3b • S1 • S0)
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.
