FACT DATA
FUNCTIONAL DESCRIPTION
The MC74AC352/74ACT352 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

Zb = Eb

The MC74AC352/74ACT352 can be used to move data
from a group of registers to a common output bus. The
particular register from which the date came would be
determined by the state of the Select inputs. A less obvious
application is as a function generator. The MC74AC352/
74ACT352 can generate two functions of three variables. This
is useful for implementing highly irregular random logic.
